I have a ContextMenu, which contains several menu items which are themselves menus -- so I have a ContextMenu with sub-menus.

When I select from a sub-menu, the sub-menu closes, but the parent ContextMenu does not. It stays open on the screen until I click somewhere else.

This may be the intended behavior (I can after all explicitly close the parent menu in the action for the sub-menu), but it feels like a bug.
