FWIW, this bug is irrelevant to autoplay because appActions.autoplayBlocked doesn't get triggered. In other words, nothing blocked by autoplay.

Needs more investigation before can be resolved or addressed by the team.

In 0.19.27, autoplay default value is set to 'always allow'.

When visiting https://www.vox.com/2017/10/1/16391722/snl-papyrus-avatar-ryan-gosling?utm_campaign=vox&utm_content=chorus&utm_medium=social&utm_source=twitter the video does not autoplay.
Clicking on the embedded YouTube video to start playback adds a per-site setting of 'always allow' for vox.com. No dialog is presented to the user to inform them this per-site setting was made, or even asking permission to do such an action.

Actually I take my previous comment back because I just saw the exception thrown from chromium DOM Exception: play() can only be initiated by a user gesture

Closing in favor of #11527.
