As we do elsewhere in this file, please include a comment with the text from the media session spec to explain why this is happening:

// https://mediasession.spec.whatwg.org/#activating-a-media-session
// 6.3. Activating a media session from a media element
// When the play() method on a media element is invoked and ...
// 1. Let media session be the value of media element’s current media session.
// 2.  ...

etc.
