    windowAttentionHandler: Follow app policy for attention notifications
    
    While window attention notifications are created by the shell itself
    rather than applications (most likely as a result of focus stealing
    prevention), users still commonly link them to the application for
    which they are shown. It makes therefore sense to follow the appropriate
    policy set by the user rather than showing them unconditionally.
