The following two tests crash in MediaPlayerPrivateGStreamerBase::copyVideoTextureToPlatformTexture() while asserting on a zero-ID texture:

- fast/canvas/webgl/texImage2D-video-flipY-false.html
- fast/canvas/webgl/texImage2D-video-flipY-true.html

The GstVideoFrameHolder constructor returns early for some reason, never mapping the video frame and retrieving the texture ID.

Backtrace:
