Specification: https://github.com/WICG/mediasession/commit/9491b7fea6c2663ccfc40232c7bdcc12ba21d1bb
Summary
Adds a media session action handler for "seekto". An action handler is an event tied specifically to common media function (e.g. pause, play).
The "seekto" action handler will be called when the site should move the playback time to a specific time.
Also adds a MediaSessionActionDetails dictionary that will be passed when an action handler is called. This is used as a base for passing additional data for "seekbackward", "seekforward" and "seekto".
Motivation
We should add support for "seekto" since this action is supported by the platform and allows sites to provide a better experience.
