CSS only working on zoomed in page - css

Question

I've an odd problem. my CSS only works on the zoomed page. When the page is at 100% size and I right click on the input the CSS doesn't work, I've to zoom in to 35% or lower for the contextual menu to appear. If I zoom out to 50% it disappears again.
The part of my code that causes the problem is in this JsFiddle http://jsfiddle.net/6ny94/1323/
Here is my complete CSS:

Your can solve the issue by setting $("#cntnr").css({"left": e.pageX-3, "top": e.pageY-3}); so then mouse cursor will appear within the contextmenu and...
function setInputSelection(input, startPos, endPos) {
input.focus();
if (typeof input.selectionStart != "undefined") {
input.selectionStart = startPos;
input.selectionEnd = endPos;
} else if (document.selection && document.selection.createRange) {
// IE branch
input.select();
var range = document.selection.createRange();
range.collapse(true);
range.moveEnd("character", endPos);
range.moveStart("character", startPos);
range.select();
}
}
$("[id*='headline']").bind("contextmenu", function(e) {
e.preventDefault();
$("#cntnr").css({"left": e.pageX-3, "top": e.pageY-3});
$("#cntnr").fadeIn(200, startFocusOut);
});
function startFocusOut() {
$(document).on("click", function() {
$("#cntnr").hide();
$(document).off("click");
});
}
$("#items > li").click(function() {
$("#headline1").val($(this).text().replace("fallback", " "));
var input = document.getElementById("headline1");
setInputSelection(input, 9, 10);
});
#items {
list-style: none;
