I am not sure I agree. The mnemonics apply to the current menu, i.e. the lowest 
menu in the hierarchy with a selected menu item. If we changed that behavior we 
would also be changing it for the situation when a menu has a menu item which 
has a submenu; if the menu item was selected the submenu would be displayed and 
the mnemonics would apply to the submenu.
