    Fix linkmap not updating with TextView size changes
    
    The linkmap widgets need to update when the sizes of their associated
    TextViews change. Currently, TextView size changes only occur with other
    events that end up causing a repaint, but with per-pane MsgAreas the
    sizes will change independently.
