This will need to be revisited.
Remove a dummy "return;", and remove an unused parameter.
PopupMenu.PopupMenuManager and MessageTray.FocusGrabber had a lot of code in common. Let's refactor this common code out into a new class, "GrabHelper". This replaces FocusGrabber completely, and nukes half of PopupMenuManager.
