    popup-menu: Add minimal handling of open/close to Sections
    
    SubMenuMenuItems close automatically with their parent, however
    closing fails when the parent item is a MenuSection, as those
    currently ignore any open()/close() requests.
    At some minimal handling by emitting the 'open-state-changed' signal,
    so children like SubMenuMenuItems work as expected.
