I now also see this when opening the in-content Tools/Options dialog. And probably also the ones introduced in bug 1021618.
This is still happening in current nightlies, and has become more apparent now that Settings has also been moved to a content tab. Blair, any good idea about why this is happening?
No :\ Lets get this in the backlog.
