>>> This is a request for WebKit's position on the "EME MediaKeySession
>>> Closed Reason" proposal:
>>> - W3C EME spec issue/explainer:
>>> - W3C EME spec Pull Request:
>>> - Previous Media Working Group meeting discussion on this topic
>>> (with Jer Noble):
>>> A MediaKeySessionClosedReason is proposed to indicate the reason for EME
>>> MediaKeySession closure, and the `closed` attribute would return a
>>> `Promise<MediaKeySessionClosedReason>` instead of the current
>>> The current EME spec says "the CDM may close a session at any point,
>>> such as when the session is no longer needed or when system resources are
>>> lost". However, there's no way to specify the exact reason for session
>>> closure. In some cases, this is part of normal user flow, e.g. user close
>>> laptop lid to put the device into sleep mode, where the player should
>>> resume playback. In some other cases, this is due to some unrecoverable
>>> fatal error.
>>> This proposal updates the `closed` attribute on MediaKeySession to
>>> handle session closure differently based on the reasons.
