I just noticed this on the trunk builds

I have a bookmarks toolbar whose contents overflows off the right side. If I open one of the right-most visible folders, and mouse over its contents, the entire bookmarks toolbar item shifts to the left (either off of the toolbar or behind any other items on the toolbar).

Regression range:
good: http://hg.mozilla.org/mozilla-central/rev/120667a01fd2 (2010-01-11)
bad:  http://hg.mozilla.org/mozilla-central/rev/a43e2f7eda8f (2010-01-12)
https://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=120667a01fd2&tochange=a43e2f7eda8f

My guess this is a regression from Bug 526394

Reproducible: Always

No, this bug had nothing to do with dragging.. plus, it's already been fixed.
Sorry for not closing it earlier. I kind of forgot about it.
