Steps to reproduce:
Set css('overflow') to 'auto' (was 'visible') on container object (div in this case) in js (interval event)
Nb no material effect on container as contents don't overflow
Actual results:
Active drop down (<select>) retains focus but collapses, making item selection impossible for the user by mouse click
Expected results:
All other browsers tested keep the drop down list open when the css change had no material effect on the container

Hi Martin,
Can you provide a complete, self-contained, minimal testcase here? Please also mention the Firefox version on which this issue occurs.
Thanks!

Simple test code below. Version is 62.0.3 (64-bit) on Windows 10 Home fully updated.
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>Untitled Document</title>
</head>
<body>
<div id="test" style="width:600px;height:500px;background-color: #B13C3E">
<form action="#" method="post">
<select name="os0">
<option value="option 1">option 1</option>
<option value="option 2">option 2</option>
<option value="option 3">option 3</option>
<option value="option 4">option 4</option>
<option value="option 5">option 5</option>
<option value="option 6">option 6</option>
</select>
<input type="submit">
</form>
</div>
<script> var myVar = setInterval(myTimer, 1000);
function myTimer() {
var d = new Date();
var x=document.getElementById("test").style.overflow;
if ((x=='visible') || (x=='')) {document.getElementById("test").style.overflow = 'auto';}
else {document.getElementById("test").style.overflow = '';}
console.log(d);console.log(x);
}
</script>
</body>
</html>

Reproduced the issue using the test code above on the latest Firefox Nightly 64.0a1 (2018-10-17), Firefox Beta 63.0 and Firefox Release 62.0.3.
Setting a component in order to involve the development team to review this issue.
Thank you for the report and testcase!
