The list item images on this page aren't to the left of the list items. Instead, they are offset down and to the right. They don't always show properly when scrolling. I'll attach an image if I can figure out how. I had this problem on my own page (http://www-cs- students.stanford.edu/~amitp/gameprog.html) but it went away when I fixed some bad HTML/CSS. So my guess is that Mozilla isn't dealing with bad HTML/CSS properly, and some invalid values are getting into the style sheet. (I haven't checked to see if ciwas-mFAQ.html validates, sorry, but Mozilla shouldn't be rendering improper HTML this badly.)
Confirming bug. This only happens the first time the page is loaded. I think the problem has to do with moving the image once it is loaded and the (nonzero) image dimensions are available. (Does that count as an incremental reflow bug? Marking as such.) Testcase to be attached. (Also need to check for duplicates.)
Actually, I believe this is a duplicate of bug 36703, which is already [nsbeta2+][6/15]. *** This bug has been marked as a duplicate of 36703 ***
The bug this was duped against is now fixed, and the testcase and test page now render correctly with Linux build 2000103121. Verified dupe.
