Firefox 3.6 and IE9 preview pass.

I had some trouble parsing the original summary - hopefully the reworded one is better. I wanted to reword even more, but then the relationship to IE test suite would be lost. Maybe we should have a meta bug for these to avoid filing duplicates with different titles.

<style type="text/css">
  body { color: blue; }
  div { color: red; }
</style>
<script>
  // Should raise an exception
  document.styleSheets[0].insertRule("@import url(testStyle1.css);", 1);
</script>

I looked into this, the problem is not that there is no exception thrown (there is already a test for that in the LayoutTests). The problem rather is that the check after the exception catch relies on backgroundColor returning transparant, where WebKit returns rgba(0, 0, 0, 0). So either the linked test needs to be fixed (may be unlikely) or we need to return transparant instead of rgba(0, 0, 0, 0). If there are plans to do that anyway this issue could be closed. Thoughts?
Cheers,

Rob.

Is this a dup of bug 36281?

Hello Simon,

> Is this a dup of bug 36281?

I think so. However if you try the linked original MS testcase trunk still seems to fail it? So either that bug was closed incorrectly, the original test changed or the fix was thought to mean "good enough" anyway. Unless I am missing something, IMHO best thing may be to close this one aw well and consider either fixing the transparant vs.rgba issue or contact the original testcase writers to make it more tolerant.
Cheers,

Rob.

The fix for bug 36281 was partially reverted, because it caused a regression. See bug 36700.
