>+        Simplify logic to prevent App Nap in WebPage. We do not need both m_userActivityHysteresis and
>+        m_userActivity since UserActivity is already a HysteresisActivity. We had 2 levels of
>+        HysteresisActivity stacked on top of one another. Also rename "process suppression" to "app nap" as
>+        I find it clearer.
