Video element in desktop Chrome is not resized when remote iOS client rotates the device

Reported by yu...@appear.in, Nov 7 2017 
UserAgent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_13_0) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/62.0.3202.89 Safari/537.36

Steps to reproduce the problem:
1. Launch AppRTC Mobile on iOS device.
2. Enter a room from iOS when device is in portrait orientation.
3. Enter the same room from Chrome.
4. Open Javascript console in Chrome and paste the following code:

document.querySelectorAll('video').forEach(videoEl =>
    videoEl.addEventListener('resize', () => console.log(videoEl.id, videoEl.videoWidth, videoEl.videoHeight))
);

5. Rotate iOS device to landscape and back to portrait.

What is the expected behavior?
'resize' event is performed for remote video element and there is an output in Javascript console when iOS device is rotated to landscape and back:

remote-video 640 480
remote-video 480 640

What went wrong?
Nothing happens, 'resize' is not called. Web app cannot adopt to video proportions change.

Did this work before? N/A 

Does this work in other browsers? Yes

It is partly a regression, it used to work with vp8 codec in Chrome 59 but never worked with h264. Now it doesn't work with any of the codecs.

CVO header extension was negotiated as both offer and answer SDPs include "extmap:4 urn:3gpp:video-orientation" (see attached dump for details).

Works as expected in Firefox 56.0.2

AppRTC mobile version that I used is built from recent commit in WebRTC master branch: 3111e5fb48dd5c58e5669119081add277c1dd068

I cannot reproduce the issue with Android AppRTC. This can be a iOs AppRTC specific problem. tkchin@ can you help with triage?

I think I have similar problem.

I have WebRTC server based on WowzaStreamingEngine software.
I have WebRTC client to recieve live video stream from the server.

Live video stream may change resolution dynamicly.

What went wrong?
When resolution changes to different - the video stop playing, audio still playing(If refresh page - video continue playing in new resolution). When resolution changes to default the video continue playing.

Just to clear things up, I reported this before, but was slow with the feedback so the old issue was archived: https://bugs.chromium.org/p/chromium/issues/detail?id=767511
