<video> does not play audio for a media stream that has stopped video track

Reported by naan...@gmail.com, Oct 26

Issue description

UserAgent: Mozilla/5.0 (Windows NT 6.3; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/70.0.3538.77 Safari/537.36

Steps to reproduce the problem:
1. use sample here: https://codepen.io/anon/pen/BqrWYQ
2. press start
3. notice that there are no sound coming from speaker

the sample stopped the video track before the connection finish establishing, but audio track is still live.
checking chrome://webrtc-internal shows stats that suggest the audio track is connected and receiving data

What is the expected behavior?
at step 3, there are audio playing since the audio track is still live

using the same sample on Firefox resulted in audio playing while video stream has stopped

What went wrong?

something about how <video> element handling a media stream with muted/ended video track and live audio track that causes audio to not be played at all

Did this work before? N/A

Status: Untriaged (was: Unconfirmed)
Able to reproduce the issue on Mac 10.13.3, Win-10 and Ubuntu 17.10 using chrome reported version #70.0.3538.77 and latest canary #72.0.3598.0.
This is a non-regression issue as it is observed from M60 old builds. 
Hence, marking it as untriaged to get more inputs from dev team.

Thanks...!!
