    Enter submenus when activating their parent item
    
    This gives consistent behavior with e.g. Qt, Mozilla's suites and
    LibreOffice (with non-truly native backends like "gen" and "gtk",
    but unlike "gtk2" and "gtk3" ones that probably use true GTK menus).
    
    This behavior is expected by at least some accessibility users, and
    it seems good to behave like other common applications and toolkits
    in this area.  There should be no issue in doing so either for current
    users, as it only enters the submenu instead of not doing anything.
