Comment 35 for bug 197781

Seems like a regression to me, since I can't reproduce anything like this in Firefox 2 on Mac.

https://bugzilla.mozilla.org/show_bug.cgi?id=330458#c29 has the steps, which are simple to follow.

Case that it *blocks* the release?: when switched to after following the above steps, the preference panels' contents will be empty until the window is closed and reopened. I had as many as three panels in this state while testing.

(Additionally, there is a smattering of embedding issues which I don't really claim to fully understand.)
