Right now the VRVSyncProvider connects to the most recently created VRDisplay. We need to know when a VRDisplay gains focus and reconnect it to the VSync provider.
This is half blocked on issue 686232 , because currently we don't/can't know when the VRDisplay gains/loses focus due to app switching or multiwindow. However, we should be able to fix this for tab switching, or having many magic windows on one page.
