The issue is reproducible also by performing the following actions on the page after step 3 (only after the play button appears on the video, without clicking on allow)

Mouse: Left click, Right click
Keypress: All keys except non-printable characters and keys that handles the browser

The video should start playing on site after each user gesture, but in fact the result is the same as above. The video doesn't start, the same picture with play button is shown.

This is not a bug. Clicking "Allow" means that we would allow video starts to play when they call video.play() or video with "autoplay" keyword before the site gets user activation. That is, we give the *permission* to website after user clicking "Allow" or activating by user gestures.

However, it doens't mean owning the permission would automatically start the video. In this case, it seems that CNN shows the play button after they stop calling video.play, and they want to let user manually start the video by the play button.
