    Ignore `highlight-nonselected-windows' for same buffer in two windows
    
    * lisp/simple.el (redisplay--update-region-highlights): Update.
    
    It looks really weird when the same buffer is opened in multiple
    windows and `highlight-nonselected-windows' is t. Especially when the
    mouse is pressed.
