When an HTML element renders a scrollbar, the scrollbar does not respect the z-index of the HTML element. The result is that the scrollbar floats above all other content thus breaking the element layering on the page.
Reproducible: Always
Steps to Reproduce:
Example HTML below demonstrates the problem. The Red div should be painted on top of the div with the text content. This is true for everything but the scrollbar.
<html>
<body>
<div style='position: absolute; top:0px; left:0px; height:100px; width:200px; overflow:auto; border:solid black 1px; z-index:10;'>
1<br>
2<br>
3<br>
4<br>
5<br>
6<br>
7<br>
8<br>
9<br>
10<br>
11<br>
12<br>
13<br>
14<br>
15<br>
</div>
<div position:absolute style='position:absolute; top:15px; left:150px; width:100px; height:100px; background: red; z-index:100;'/>
</body>
</html>
Actual Results:
div with text content's scrollbar is painted on top of the red div
Expected Results:
red div should be painted on top of the scroll bar
Note the behaviour is correct with FF on windows XP, so this may be an issue with the native toolkit?
