First frame of MSE video obtained through drawImage or texImage2D is empty When JS obtains the video frame, the MSE implementation switches decoding from "layer" to "decoder session". This loses the current frame. Affected bug 228821 where texImage2D-mse-flipY-true.html would print errors to console for the first frame upload.
