GeckoSurfaceTexture could bind to only one GL context at once. With WebRender, GeckoSurfaceTexture is soon bounded to sharedGL on render thread. It caused the problem if GeckoSurfaceTexture is rendered to WebGL. It could happen only for video's GeckoSurfaceTexture. To avoid the problem, the GeckoSurfaceTexture is bound to gl context when it is actually rendered on WebRender.
