Isn't bug 234393 actually a duplicate of bug 211562? The last line in the testcase is really obscured. There is no vertical scrollbar. But you can scroll the page using the arrow keys. That is interesting. I can confirm this with Firebird 20040128. It was working in Moz 1.5.

I have even seen a case where a div positioned at bottom: -20px; appeared OVER the horizontal scrollbar (was drawn at a position outside of the page but obscured the scrollbar). The div had a style so that when hovered, it changed to bottom: 0px;. In that moment the position was computed correctly and the div moved up so that it exactly touched the scrollbar on its top. That is very interesting but I am working on a test case for this (a have a page which does this everytime, but is very complicated, using JS and such stuff). I can 100% reproduce it everytime but can't yet publish a testcase :(

I can no longer reproduce the bug with firefox 0.10.1 on the attached testcase. Can somebody else?

I am still able reproduce this bug in Mozilla 1.8a4

I can see it too in Firefox 1.5b1. There also is a vertical scrollbar on the right. That seems to be a regression.

From bug #211562, another testcase: https://bugzilla.mozilla.org/attachment.cgi?id=175841 Here it's a pair of nested divs.

I believe this bug should be resolved as DUPLICATE of bug 44192. attachment 126993 [details] is excellent and should be made available at bug 44192.

This is not the same situation as bug 44192 -- that's for fixed-positioned elements. The positioning rules are different.

Ok, Boris. Thank you for clarifying this.

I don't see this on Mozilla/5.0 (Macintosh; Intel Mac OS X 10.5; rv:2.0b3pre) Gecko/20100725 Minefield/4.0b3pre, can anyone else still reproduce?
