+        cost of HitTestResult(IntPoint()) in EventHandler::mouseMoved()
+        from ~1700 cycles to ~300 cycles.

What are the reasons to believe that it's worth making the code more complicated for this? The improvement is on microsecond scale.

Historically, we had a lot of success making many 1% performance improvements, but it's not obvious if there is any scenario where this would provide 1%.
