-    Fix focus handling with multiple awesome instances
-    
-    When there are multiple X11 screens (i.e. :0.0 and :0.1) for zaphod mode
-    style X setups, this triggers a refresh of focus when the instance
-    running on a particular root receives the mouse
-    
-    Fixes https://github.com/awesomeWM/awesome/issues/599.
