lib Update Request

Action definitions that have existed for years have been removed with the latest LKG update for 4.9+
3a6d7e9#diff-796971dc74a3f3cd77ca0a3a776d6fe27ab224cd501d9652dbeffcf45ba0f058L18186

When 4.8.3 still has these definitions https://github.com/microsoft/TypeScript/blob/v4.8.4/lib/lib.dom.d.ts#L18186

Media Session Standard specification has information about these types of actions https://w3c.github.io/mediasession/#mediasession It is difficult to classify these things as experimental, because the standard itself is still Draft

Configuration Check

My compilation target is ES2015 and my lib is the default.

Missing / Incorrect Definition

MediaSessionAction has lost hangup, togglecamera and togglemicrophone options.

Sample Code

 navigator.mediaSession.setActionHandler('togglecamera', () => {
   // toggle camera
 });

MediaSession is only implemented in one browser engine, but Typescript requires two implementations for draft standards to be included in the standard lib. See for example: microsoft/TypeScript-DOM-lib-generator#821

In 4.9 the parts of the standard that were mistakenly included were moved out of an upstream definitions repository and as a result, out of Typescript: microsoft/TypeScript-DOM-lib-generator#1400

@sandersn thanks for the clarification!
