webrtc: onRemoteDescriptionError:InvalidAccessError:Failed to set remote answer sdp: The order of m-lines in answer doesn't match order in offer. Rejecting answer.

Reported by cubus...@gmail.com, Yesterday (43 hours ago) 
UserAgent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/72.0.3626.28 Safari/537.36

Steps to reproduce the problem:
This is a call from Chrome/webrtc to a sip client via our gateway, it works perfect with the official (non-beta version and with old versions), so something got broken in this beta version. Also, other than what the error message claims, the order of m-lines in the offer and answer is identical, I checked this.

What is the expected behavior?
answer is processed and call gets audio connection

What went wrong?
processing aborts because of error at setRemoteDescription.

Did this work before? Yes it works for example on 71.0.3578.98

Does this work in other browsers? Yes

Chrome version: 72.0.3626.28  Channel: n/a
OS Version: 10.0
Flash Version: 

this is a call from a audio+video webrtc client to an audio-only SIP phone.

this is due to the unified plan transition. hbos PTAL, I thought the handling of answers without mid was fixed before you enabled this by default...

potential duplicate of 901787 -- which should be in the latest beta.

I believe a fix for this error (https://webrtc-review.googlesource.com/c/src/+/115683) was released in 72.0.3626.53, your version 72.0.3626.28 is older.

Can you see if you can repro with a more recent Beta?

I'm suspecting (just like philipp) that this is a duplicate of  https://crbug.com/901787 .
