When CA layers are not remotely hosted in both the GPU process and the WebContent process, it is not
guaranteed that the remote context ID will be set in the HTML media element when entering fullscreen.
This patch works around that by delaying setting up the fullscreen until the video dimensions are set.
At this point, the remote context ID should be available.
