At the URL given, a div will disappear for no reason at all.

Go to the "Today's Poll" Section, and at the bottom of that div, around "View
Results", just move your mouse around. The poll div, as well as the funny image
div, 90% of it will disappear. This is a very odd glitch, and has nothing to do
with how the site is coded (xhtml 1.1 and valid css).

Reproducible: Always
Steps to Reproduce:
1.
2.
3.

Actual Results:  
"Today's Poll" and "Newest Funny Images" div disappear

Expected Results:  
Not deleted 90% of the div

Attachment: simplified testcase

This is the simplest I could get the testcase, to reproduce the problem. I
added teh background:blue; in .headpoll so we can still see the background
disappear. Remove anythng else from the css resulted in the bug failing. Also,
removing the <strong> tags from the link also resulted in the bug failng. This
is very weird IMO.

URL will no longer work, because I removed the height attribute so the bug
wouldn't work on my site: however, it still does so in the testcase.

Attachment: further simplified testcase

Further simplified (and slightly different) testcase.
Styles are specified for the DIVs individually, so that only the styles
required to reproduce the bug are applied to each DIV.
Also - using overflow:hidden instead of overflow:auto (they both show the same
behaviour).
Hovering the green div (or changing the font size using ctrl+/ctrl-) causes it
to shrink to 20% (which is what it has specified as "height") of its parent
div.

Requesting block 1.1 and removing URL

you don't need to request blocking the gecko milestone and blocking the aviary
releases. one or the other should do and it's generally best to pick it based on
the bug's product.
