    Respect gtk-keynav-wrap-around in the global change-page handler
    
    We have a global-handler for Ctrl+Page{Up,Down} that is used in some
    situations (basically, when the notebook is not focused). It does not
    respect the wrap-around GtkSetting though, so the final experience can
    be inconsistent.
