This line seems to break media button functionality

p.get(this)[playerFactory].player.enablePlayButton();

I am currently writing my own little media player app and try to get the media buttons working. For a plain HTML audio element, it works perfectly, but not with the IcyMetadataPlayer.

I finally could trace the issue back to this line. The called method completely clears any context from the current mediaSession by nulling the attributes of the audio element. Apparently, that disconnects the mediaSession from that specific audio element.

So, for a playing audio stream...
... the expected behavior is: Media buttons pressed in any order trigger their respective action
... the current behavior is: Media buttons work until I press pause. After that, media buttons don't work anymore until I restart the stream manually

I could also reproduce the issue your Bare HTML Demo (didn't try the others).
Browser: Opera 99

PS: I also checked older versions of IcyPlayer - Media Buttons worked until 1.17.5
