    Attempt on #12066.
    
    Some lfuns are handled directly in GuiApplication while handling
    of menu hiding in fullscreen was done on the level of GuiView.
    
    We'll see if this code movement breaks in different scenarios,
    but quick grep suggested that the only other way to guiview
    dispatch is through drag&drop when menu isn't involved.
