Title: menubar: Hovering on sub-menu-less menu-items should close open submenus

Given a menubar with

[X] [Y] [Z]

Where X and Z both have sub-menus, but Y does not,
if the user mouses over Z its sub-menu displays as
expected. But hovering over Y does not close Z's
menu. The user has to hover over X to close Z's
sub-menu. This is unexpected.
