This is *not* the correct solution; if you change 
is_attached_menu_window, the attached menu appears at the wrong place in 
the at-spi hierarchy.

So, the problem is not in is_attached_menu_window - the window should 
NOT appear there, it should appear elsewhere, as a child of the widget 
to which it is attached.
