When I set negative z-index to DIV that have a scrollbars - it's not applied to scrollbars. When DIV hidden via css rule "display:none" - scrollbars hiding and all right.

This bug related *only* for Mac-version of FF. Not applied for Win-version.

Reproducible: Always

Steps to Reproduce:
1. Create DIV with style="width:100%; height:100%; background-color:#f00;"
2. Create another DIV with style="width:100px; height:100px; overflow-x:auto; overflow-y:scroll; position:absolute; top: 100px; left: 100px;"
3. Put some content to second DIV to make it scrollable.
4. Set first DIV z-index to 10
5. Set second DIV z-index to negative 
Actual Results:  
See lonely scrollbar on the first DIV. :(

Expected Results:  
I should see only first DIV w/o all that stuff.

Are you able to test a firefox trunk build (from ) and see if the problem is fixed there?
Yes, this problem fixed in 3.0a8pre.
Should I expect fixing this bug in 2.x branch?
If it is a regression on the 2.0 branch (ie: worked on an older version on 2.0 but no longer works on then it would be a candidate for being fixed.

But if it's always been present since Firefox 2.0 release, then it's unlikely to get patched.
It is an age old bug on Gecko. And yes, it is fixed on trunk.
