    layout: Set initial visibility of fullscreen-tracking chrome
    
    When chrome is added with the trackFullscreen parameter, the actor's
    visibility will be updated automatically whenever its monitor's
    fullscreen state changes. However as we currently ignore the fullscreen
    state at the time the chrome is added, the initial visibility may well
    be incorrect - fix this by updating the initial visibility as necessary.
