    widget: Always update the CSS node
    
    Anybody who keeps their own CSS nodes around or wants to order CSS nodes
    different from widgets will from now on have to do it manually all the
    time.
    
    This is outdated behavior, nobody should be doing either of those two
    things.
    
    Also, the correct case is much more common, and not doing it
    automatically was causing bugs.
    
    Fixes #3280
