Is this a bug in firefox 8.01? When scrolling up, the O overwrites the adressbar, bookmarkbar and part of the main menu. Upgrading to 9.01 made the effect less visible, since now only a small part of the O can end up covering the firefox UI.

EDIT: It can in fact cover parts of the main menu in 9.01 just as in version 8.

That surprised me as well. The first A in "SCROLLORAMA" goes over the scrollbar in Firefox 9.0.1 on Linux.

Could this be a security bug? Is there other ways scrip+css can take over the rendering, which I guess is done by XUL? Advanced click-jacking?
