Now, maybe Ingo (according to git blame) can chime in here and provide
an explanation. It looks like the layout aware BMenuBar constructor
calls a non-layout version of BMenu with an empty BRect() parameter.
I'm guessing this is so that a BMenuBar doesn't act like a layout
aware BMenu.
It looks like the magic happens in BMenu::_UpdateWindowViewSize()
which gets called on AttachedToWindow() and AddItem() at least.
