Parent/child relationships in GTK+ refer to physical containership -
that is, 

 widget->window is always a child of window owned by the parent
 widget->allocation is contained completely within widget->parent->allocation.

Now, there is an ugly exception to that for GtkHandleBox because
of it's reparenting nature, but we don't want to extend that
exception elsewhere.

So, we use GtkMenuShell->parent_menu_shell instead to handle this.
