To make this fail, you have to scroll the page.

That's an incompatibility with YUI, which is used there. YAHOO.util.Dom.getY returns a value which contains the scrolled offset two times.

Actually, YUI isn't used there, although it's mentioned in one of the scripts. Anyway, it's the same underlying problem.

See vB_Popup_Menu.prototype.fetch_offset in <http://futuremark.yougamers.com/forum/clientscript/vbulletin_menu.js>, which uses getBoundingClientRect if available.

[Martijn Wargers (dead)]

I suspect this would be fixed by the patch for bug 392671, especially since you need to scroll the page to get the bug.

Comment 4

[Dão Gottwald [:dao]]

This might be a duplicate of bug 392671. But your testcases confuse me a bit -- I'd say let's keep this open until it's clear that the other patch will actually fix getBoundingClientRect under all circumstances.
