I recently noticed that notification that firefox shows for Google Chat
are displayed as ordinary windows by xmonad as opposed to corner popups.
Is this a recent change or did I simply not notice this behavior before?

Anybody else hit this? Any workarounds?

The windows have somewhat different properties (Override Redirect State)
which may explain the delta in behavior.

firefox:                                                   chrome:
