    Don't clear selection too eagerly
    
    When the current submenu in a GtkPopoverMenu is selected, and we
    are editing its submenu child property, we get change notification
    for the popovers visible-submenu property. Don't clear the selection
    in this case because the visible submenu did not actually change
    to a different widget, it just changed its name.
