Description Chris Lord 2021-05-20 00:57:11 PDT 
The clipped overflow rect changes depending on whether asynchronous compositing is being used. As this rect is used outside of rendering, it would be useful to be able to specify a VisibleRectContext in this function to control the behaviour with respect to compositing properties. This behaviour is currently breaking spatial navigation when asynchronous overflow scrolling is enabled.
