1264832 - [EME] Delay resolution of navigator.requestMediaKeySystemAccess promise until Widevine CDM is downloaded

Status: RESOLVED FIXED

(Core :: Audio/Video: Playback, defect, P1)

Description

[Chris Pearce [:cpearce (Not reading bugmail)]]

If the Adobe GMP isn't downloaded, we'll delay the resolution of the navigator.requestMediaKeySystemAccess() promise until the Adobe GMP is downloaded, or 60 seconds has passed. We don't do this for the Widevine CDM, but we should.
