More info. 
After pressing the power key, MediaDecoder::SetDormantIfNecessary is not called.

This problem can be found in non-MSE case. 
And only playing video via browser can hit this problem. Using video APP cannot.

    Reproduce rate: 5/5

Repro STR:
1.Connect wifi
2.Open Browser app and enter youtube website.
3.Play a video.
4.Press Power key to lock screen.
**Video will continue to play. --KO
Note:
1.If you open Camera app->recording a video and save->preview the video->press Power key when video is playing in camera, then the video still continue to play.
2.When you play the video in Video app,this bug does not exist.

It is by design. See Bug 906612 Comment 9.

Video app change HTMLMediaElement.mozAudioChannelType to "content" to prevent this.

If we want to fix this, we need to ask youtube to set HTMLMediaElement.mozAudioChannelType to "content".

Thanks for the info!
To me, this is not a good UX. Most people should expect the playback to be stopped.

We're not supporting Firefox OS any more, so this is unlikely to see new work. Closing as incomplete.
