<pre>We have several media stream tests crashing with this assertion in OpenWebRTC:
owr_video_renderer.c:314:owr_video_renderer_get_element: assertion failed: (flip)
Each test has been broken since it was added (though some of the tests originally timed out instead of crashed). The affected tests are:
fast/mediastream/apply-constraints-video.html
fast/mediastream/MediaStream-video-element-displays-buffer.html
fast/mediastream/MediaStream-video-element-video-tracks-disabled-then-enabled.html
fast/mediastream/MediaStream-video-element-video-tracks-disabled.html
Example backtrace:
