Some days ago I was wondering how it works and was kinda surprised just now that this is from mozilla itself. Reading the project Readme makes this even straight up sound like a privacy addon. I wonder why this is not natively supported.
In I Switched to Firefox and Never Looked BackI use Video Background Play Fix [1] (along with uBlock of course). "Firefox for Android can continue playing video even if you switch to another tab or app. However, sites can detect these user actions with the Page Visibility API and the Fullscreen API. This add-on is designed to block events and properties exposed by the APIs."

They certainly did – https://github.com/mozilla/video-bg-play for example is a very simply content script which doesn't use any special extension APIs at all and so would have worked right from the start, yet it still took several months until it was eventually added to the list of officially "blessed" add-ons.
