    header-bar: Don't disable navigation actions when history is cleared
    
    There's no reason to do this. The history service is not needed for the
    back/forward list to work properly, so no reason to disable back/forward
    after clearing history. And it's disabling the stop/reload action, too,
    which doesn't make any sense. Especially since  there is no code to ever
    enable it again.
