+Subject: [PATCH] Prune superfluous calls to SetCompositorPending
+
+We only need to call SetCompositorPending with the pending cancel
+reason if the animation is running on the compositor.
+
+The stack trace on the bug report showed a significant time being
+spent in HasProperty. The timing was also optimized in this CL to
+prevent unnecessary duplicate calculations.

+Bug: 382394791
