HTML Media Capture Test: capture video with 'user' facing mode to produce one video file

Clear all camera/microphone permissions before running this test. If prompted for permission, please allow.

After hitting the button below, the camera must be launched with self-view mode.

(Note: If the user agent is unable to support the preferred facing mode, it can fall back to the implementation-specific default facing mode.)

Capture a video and then confirm the capturing.

Note: All the actions need to be done in 60 seconds, otherwise it will get TIMEOUT.
