**** You need a VPN to Hong Kong in order to watch the vidoes.

Steps to reproduce:
1. Set media.autoplay.default to 0 (allow autoplay).
2. Go to http://viu.tv/encore/plan-b/plan-be1mo-goo-jun-him-ging

The video should auto play now as expected.

3. Set media.autoplay.default to 2 (prompt)
4. Go to http://viu.tv/encore/plan-b/plan-be1mo-goo-jun-him-ging again.


Actual result:
Auto play is blocked but doorhanger is not shown.


Expected result:
Doorhanger shows and let users allow autoplay for the domain.

This is an intended behavior which would pause autoplay video when the video is changing itself from non-audible to audible.

In this case, the video in viu.tv is muted when it asks for play request, and then it immediately umute itself after getting the permission to start playing. We don't allow this kinds of trick which is lying to UA in order to get the autoplay permission.
