Re: [webrtc-pc] Clarify unmute event must fire on receiver.track AFTER sRD(offer) succeeds (#2880)

DTLS setup can't happen until offer/answer is completed, and before DTLS setup is complete, you don't have the keys to decrypt SRTP packets.
So early media can't happen on initial offer/answer.

It *can* in theory happen on subsequent offer/answer, however.

When the WG discussed this in 2015 or so, it was considered "not so important we have to have extra code to accomodate it".
