Navbar is stretched in full height only on Safari - css

Question

I've got a navbar that looks briliant in all browsers except on Safari - it's stretched at full screen height (but not width).
In all browser it looks like this: https://imgur.com/KB1sBlM
And in Safari...well: https://imgur.com/g1L6wxe
My first assumptions and suspicions are position:sticky, linear-gradient and box-shadow but it's only my suspicions.
Not even sure whether it is a CSS problem. I use also react-scroller there, so my that's the issue?
Here is my SCSS code:
Navbar general:
.thematic-area-nav {
position: sticky;
position: -webkit-sticky;
width: 70vw;
top: 0;
left: 0;
z-index: 2;
font-size: 1.3vw;
-webkit-box-shadow: 0 0 25px 1px #000000;
box-shadow: 0 0 25px 1px #000000;
border-radius: 0 0 5px 5px;
background: -webkit-gradient(
linear,
left top,
left bottom,
from($color-background-primary),
color-stop(50%, rgb(237, 237, 237)),
to($color-background-primary)
);
background: -webkit-linear-gradient(
top,
$color-background-primary 0%,
rgb(237, 237, 237) 50%,
$color-background-primary 100%
);
background: -o-linear-gradient(
top,
$color-background-primary 0%,
rgb(237, 237, 237) 50%,
$color-background-primary 100%
);
background: linear-gradient(
to bottom,
$color-background-primary 0%,
rgb(237, 237, 237) 50%,
$color-background-primary 100%
);
color: black;
padding: 10px;
& > * {
color: black;
}
& > ul {
list-style: none;
display: -ms-grid;
display: grid;
-ms-grid-columns: 25% auto;
grid-template-columns: 25% auto;
}
}
Logo:
.thematic-area-nav__logo {
-ms-grid-column: 1;
-ms-grid-column-span: 1;
grid-column: 1/2;
-ms-flex-item-align: center;
-ms-grid-row-align: center;
align-self: center;
width: 100%;
height: 150%;
}
Buttons:
.thematic-area-nav__areas {
-ms-grid-column: 2;
-ms-grid-column-span: 1;
grid-column: 2/3;
display: -ms-grid;
display: grid;
grid-template-columns: repeat(auto-fit, minmax(12vw, 16vw));
grid-gap: 0.5em;
& > button {
border-top: none;
border-bottom: none;
border-right: 1px solid rgb(218, 218, 218);
border-left: 1px solid rgb(218, 218, 218);
border-radius: 5px;
-webkit-box-shadow: 1px 1px 1px;
box-shadow: 1px 1px 1px;
background-color: $color-background-primary;
font-size: 1vw;
&:hover {
color: black;
-webkit-box-shadow: inset 1px 1px 1px;
box-shadow: inset 1px 1px 1px;
font-weight: bold;
}
&:focus {
outline: none;
-webkit-box-shadow: inset 1px 1px 1px;
box-shadow: inset 1px 1px 1px;
font-weight: bold;
}
}
}
.thematic-area-nav__singleThematicArea {
& a {
text-decoration: none;
color: black;
}
& > * {
text-decoration: none;
cursor: pointer;
color: black;
}
}
Is that a CSS problem indeed?

I looked into the html/scss code from jsbin, did some cleanup and managed to achieve something I think is close to what you had in mind.
Some notes:
Avoid using vw and vh for font sizes unless there is a really good reason not to do so.
If specifying width/height in % always figure out how the browser calculates those (ask yourself "percentage of what?").
Use https://validator.w3.org/ - it helps.
Avoid mixing camelCase and-this__thingy.
Keep your code tidy.

It’s quite unlikely that react code is causing the problem. Could you copy the html that is created by your react application, the css code and create a test case with just those? It would be good to establish if the problem appears when your JS is not “enabled”. How do you feel about sharing a link to your repo?
Some side notes: putting a link inside a button does not seem right. It will most definitely fail any accessibility evaluation, also class="Obszar tematyczny 3” value doesn’t seem right, ul element should only have li as children, placing anything else inside it is, well, WRONG.
There is also quite a lot of flex box weirdness in your styles. By reading it I’m not really able to grasp your intentions. I think that you’re not fully familiar with flexbox properties that belong to flex container and those that belong to its children.
In addition to that, you could stop using * selector. Just stop. World will be a better place if you do.
