Description of Change
#19349 created an issue with nested scrollviews that was causing the layout calls to thrash. Because we were calling "Measure" on the hScroll during the layout pass, this would reset the height/width on the frame during layout, which would then cause "requestLayout" to schedule a "requestLayout" on the UI thread. Which would then cause the loop to trigger again.
This PR attempts keep the measures with the measures and the layouts with the layouts.
