The play button goes away if you click (pause) then click (play) in the video once it starts.

This isn't a bug on AMO, this is a bug in Firefox. The play button is part of the native browser controls; we don't create it.

Try visiting the page in Chrome and see the results: https://addons-dev.allizom.org/en-US/developers/builder

If you use the inspector to hide the <video> element, you can see that the play button disappears as well. That shows that it's not added by us. I couldn't see any ::before or ::after on there, either.
