As we move away from window messages and HWNDs, we will eventually want to move away from using MS::RN::ForwardWindowMessage for updating size changes. This issue is here to track the work.
Do we have an issue to switch this over to a real API that takes a size. Something like MS::RN::NotifyOfWindowSizeChanged(rns, size);
