    window: Move all attached windows with parent
    
    We'd break the loop for moving attached windows at the first window,
    meaning we'd only ever move a single attached dialogs or popup if it was
    the first window in the list. This doesn't work out well when there are
    multiple popups open, so don't break out of the loop at all until all
    windows are potentially moved.
    
    This fixes an issue in gtk4 where one or more non-grabbing popups would
    end up unattached if there were more than one and the parent window was
    moved.
