I think this is related to many other issues regarding Media (https://github.com/mozilla-mobile/fenix/issues/7370, https://github.com/mozilla-mobile/fenix/issues/10740, https://github.com/mozilla-mobile/fenix/issues/4793, https://github.com/mozilla-mobile/fenix/issues/5290) and it is still waiting on integrating the GV API into AC: https://github.com/mozilla-mobile/fenix/issues/5290#issuecomment-699902435

This should be tested along with the other issues when the new API is implemented.

With the new MediaSession API, this should be fixed on nightly. I tested with https://www.collectivecreamery.com/podcast and the media play button is showing.

However, for https://mynoise.net/NoiseMachines/cafeRestaurantNoiseGenerator.php, I tried on Chrome as well and there's no notification showing for the media. I think in the cafe case it is a site issue. We behave the same way as Chrome.

https://www.collectivecreamery.com/podcast case is fixed in nightly. Please verify. Thanks
