Monaco Editor Intellisense Not Full Height - css

I am using Monaco Editor 0.22.3 in combination with StencilJS and TailwindCSS. Everything works great, except for an annoying visual glitch in the intellisense dropdown as depicted here:
As you can see, the last suggested item is partially obscured.
I suspect it might have something to do with some style coming from TailwindCSS, but I'm pretty much at my wits end here. I tried to use the F12 element inspector to see if I can find some hints, but that is proving to be close to impossible since the intellisense dropdown disappears as soon as it loses focus.
Any hints would be much appreciated!
UPDATE 1
Here's a screenshot with a bigger editor to demonstrate that the dropdown itself does not appear to be clipped:
UPDATE 2
Here's an animated gif showing the issue when trying to debug the HTML elements using the browser developer tools:
As you can see, the dropdown disappears as soon as I click anywhere else.

The issue comes from a fairly common css class being used: .tree. Libraries such as tailwindcss add padding-bottom to it for example. To undo some of its additions for the monaco editor we added the following to our css file:
.monaco-editor .suggest-widget div.tree {
white-space: unset;
padding-bottom: 0;
}
And to get get to that solution for other libraries and styling artefacts:
It should have been quite easy but the suggestion dialog has a tendency to hide when we try to observe it. so a UI guy and I spent a while going through the playbook to try to debug it. The only successful way to inspect it was to abuse the JS debugger by running (which was a hint from a stack overflow post that I'm struggling to find to give credit), and just cause the JS engine to pause:
Run:
setTimeout(5000);
This gives us 5 seconds to get the suggestion window to show (or set to a relative amount of time to the problem). After which, you could mostly inspect it as normal with a quick shortcut:
ctrl+shift+c that brings up the debuggers element selector.
Here we are, the suggestion was from the following post:
How can I inspect disappearing element in a browser?
break on subtree probably would have worked, but we became a bit impatient stepping through the changes. ctrl+ / didn't seem to help in this case, which left the odd setTimout to save the day.

The drop down is clipped at the editor's boundaries. I actually wonder how you can see the last empty part outside of the editor.
For inspection: use your browser's dev tools to see how the containers overlap. This will avoid that the editor hides the drop down.
Update
After your update I think now that somehow the styles are messed up. You will have to figure out a way to show the popup and still navigate the DOM tree in the developer tools. Try to locate the parent and see if that popup is only hidden (it still shows up then in the tree) or if it is dynamically created or is a portal, which lives in a completely different part of the tree.
If that cannot be done then try to disable all CSS you have and see if that solves the issue. If so enable the CSS piece by piece to find the culprit.

View inherited CSS properties for hovered element

I have encountered an annoying problem while trying to debug some CSS in Chrome. I am rather new to CSS, and using Chrome's "Computed" window in the CSS developer tools has been very handy in figuring out where CSS properties I'm trying to assign are being overwritten later down the chain. (Please feel free to correct any incorrect terminology so I can be on the same page).
Here's an example of how it helped me successfully change the color for an active jQuery UI Tab:
http://1drv.ms/1yJzyec (don't have enough rep points yet to post a picture. This goes to my OneDrive.)
I need to use this approach to figure out what's going wrong with my CSS for a hovered or focused element. Here's the problem: as soon as I click into Chrome's developer tools to see the chain of inheritance for a specified element, it is no longer hovered/focused because I've clicked into the developer tools, preventing me from seeing the inheritance.
Are there any other tools out there that can help me dissect an HTML element's CSS inheritance chain in real-time?
Thanks!
Using Chrome developer tools, you can force the element to be in the hovered state.

Trouble finding the right CSS to modify

I am building a site using Drupal 7 and have run into a CSS issue. I am trying to wrap everything on this registration page in the center and at the same time reduce the width of the drop down buttons. I believe I've narrowed the problem to my logintobaggan (drupal module) css sheet. But the button "widths" seem to be from the foundation.min.css (according to chrome elements). How would you guys approach this CSS problem? I am relatively new, so please don't be too harsh ;). Thanks!

I would get Firebug or similar in-browser development tool, select the element you are interested in seeing the CSS properties for, and then see exactly which rules are being applied or overridden. You can even modify the CSS right there in the tool until you get want you want.
From such a tool, I can see that the button widths are not explicitly defined, but are basically derived from the amount of padding (5px) around the text string inside the button.
The rules are defined starting on line 41 of this file:

Debugging CSS in Google Chrome

I am writing some CSS files, but when I make a mistake, Chrome appears to just silently ignore the parts that I screw up, and renders the rest.
This makes it annoying to debug since I can't figure out what is going wrong.
So, is there a way to get Chrome to "scream at me in big red letters," so that I can spend less time finding the error and more time fixing it?
While you can not "debug" CSS, because it is not a scripting language, you can utilize the Chrome DevTools Elements panel to inspect an element & view the Styles pane on the right. This will give you insights as to the styles being overridden or ignored (line threw). The Styles pane is also useful because of it's ability to LiveEdit the document being inspected, which may help you iron out the issues. If the styles are being overridden, you can then view the Computed Style pane to see the CSS that is actually being utilized to style your document.
To bring up the Chrome DevTools window, hit Ctrl+Shift+I in a Chrome browser tab. (Command+Opt+I for a mac)

As CSS is not a scripting language, you cant properly debug it. Anyway if you know where it goes wrong you can try to tune it by hand.
Aditionally you've got the w3c validator here: http://jigsaw.w3.org/css-validator/ which may give you some feedback

CSS : Firefox right click selects all on my site...why?

I have built a context menu but have found annoyingly that when I right click on my site in firefox all text and images just seem to randomly get selected. It is not a JS issue as I have removed all JS from the site. Thinking it must be a css issue. I have never encountered anything like this before...
I don't have an example page to show I'm afraid. Has anyone experienced this before in Firefox. I am using the latest FF4.
Cheers Guys!
*UPDATE:*
Here is a pasting of the pure html from the page that is having issues,
http://jsbin.com/aneja4/3/edit
did you try to disable all your addons you have installed? maybe one of them is causing the problem.
I have FF 4 but neven encountered this problem before.
And I could be wrong but I don't know of any css code that would be able to select text. it's pure for the design and structure of the site. it will be mostlikely a js problem or something else
I have seen this too... I think it has something to do with the way the site is structured... If you have nexted divs, or a div that does not quite cover the entire page, a right click on the parent div seems to select everything in the nested div. It's quite annoying... especially when trying to build a custom context menu, or use the default menu to refresh the page...
Any fixes/changes that we should know about for FF that is causing this? I'm using FF4 and XP (yeah, yeah... corp. system)

It's likely a problem with your HTML layout that firefox is struggling to work with. But without seeing any code, it's not possible to speculate any further down that path. #JDF's suggestions may help you, though.
If you can't work it out, and can't live with it, you could just disable the ability to select text.
In Firefox (and other standards-compliant browsers), you'd use the CSS user-select: none;.
See this question for more info on how to achieve this: How to disable text selection highlighting using CSS?
This is most likely caused by having a contentEditable element on your page. Any element (other than body it seems) that contains editable content will be highlighted/selected when you right click on it in Firefox (4.0 and 5.0 is all I can confirm). If everything on your page is wrapped in a div it'll appear that the whole page is selected. If you (can) right-click somewhere on the body the regular context menu should work.
Although I can't see any instances of contentEditable in your code on jsbin, it could be added by a script that I can't see (possibly even modernizr?).
I think this is related (although it doesn't match exactly)

http://aloha-editor.org/ exhibits the same behaviour when right-clicking anywhere inside the #wrapper div.

drupal - problem with quicktabs

Hello
I have quite a strange problem using quicktabs. I used the framework theme to develop a custom look for my site. I used quicktabs in the center content area to create a tabbed look for placing links within the body. Everything is working fine. However, when I view the site in IE8 at a resolution if 1024*768, I have trouble with a few links. It seems that sometimes the first link under my buttons are difficult to click. The link is there - I can actually click it, but it is very difficult to locate - it only appears at the very beginning of the link text - it is not the first letter, it seems to be only the first pixel.
I looked at the source and everything seems to be correct - I can't figure out what could be wrong.
Has anyone seen any similar behavior that might be able to point me in the right direction for a fix for this?
Thanks for any thoughts.
Edit - I looked further into it and I think it has something to do with my CSS. I disabled css in ie8, and every link is clickable, even the ones that were difficult to locate earlier. I guess there must be an overlapping of containers or something, so I will have to start messing around with those files.
It sounds like a CSS thing, have you inspected the elements in question using the developer tools (press F12) to see whats going on?
I found the solution. In the style.css file for my theme, the .block had position: relative; applied to it. removing that bit of themeing appears to have fixed the link issue.
Thanks
