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.
