At http://turkeybot.info, whenever you have over the navigation menu, the box on
the left, the heading, will change names depending on which other box you hover
over...it's kinda hard to explain, but it's easy to see what I'm talking about
when you do it. The site is valid xhtml 1.1, and valid css, so it's not a site
problem.

Reproducible: Always
Steps to Reproduce:
1.Go to http://turkeybot.info, and hover over the navigation menu.
2.Go between different categories, and watch how the box on the left reacts.
3.



Expected Results:  
The left box should not have been affected.

Maybe there's something wrong with the menu.
Opera won't show it at all
W3C validation is ok.

Needs a testcase.

I'm seeing as css float:left for the part that changes position when you hover
over any of the menu-items.
This could very well be related to bug 132337.

Attachment: simplified testcase

I found that when both the div{overflow:auto;} and .navdata or navdataalt had
float:left; in it, the glitch occurred. However, when either overflow or float
were removed, the bug no longer worked.

So I believe overflow:auto; and float:left;, combined, are causing this error
that should not be occurring. Overflow is for scrolling if the div overflows,
which it doesn't do, and float is to position it; obviously a glitch with the
way they're being rendered.

Once again, this bug is only reproducable when overflow:auto; and float:left;
exist in this page. Removing either one of them will kill the bug.

The testcase looks almost identical to the one attached to bug 228059, which was 
marked duplicate of 132337.
