    reject x11 NotifyVirtual and NotifyInferior mouse in events
    
    these are triggered "in passing" when mouse in events occur and do
    not necessarily indicate that the mouse has entered this specific window
    
    failing to reject such events can cause mouse-based focus policies to
    attempt to set focus onto windows which are not visible, resulting in
    an infinite loop where no window is actually focused
