Blinking and resizing self-view

1. Join the conference with remote participants or use webRTC sample https://webrtc.github.io/samples/src/content/getusermedia/gum/
2. Start the camera to get self-view
3. Rotate the device
4. Take a look at the self-view while rotation

Actual result: Self-view blinks and resizes several times when rotating the device

I can reproduce this bug as well. I'm on an iPhone Pro 13, iOS 17 17.0.3.

I did the following:

1. Go to https://webrtc.github.io/samples/src/content/getusermedia/gum/
2. Make sure auto-rotate is on on my iPhone
3. Click "Open Camera" whilst holding my phone in portrait mode
4. Rotate phone to landscape mode
5. See results in video: https://www.dropbox.com/scl/fi/9i9j8a27nkqvoi3ba6scf/dekker.staging.daily.co-temp123.MP4?rlkey=z0v581clv6zehj6335uz08p6k&dl=0

I was able to reproduce the same issue on https://dekker.staging.daily.co/temp123, a WebRTC based video app. Video here: https://www.dropbox.com/scl/fi/ra1l7b2sdv5e02ok5tcxl/webrtc.github.io-samples-src-content-getusermedia-gum.MP4?rlkey=a4nq150wb651rtainxal2ur2u&dl=0

I find the zoom-in effect especially odd..!

This is the same rendering bug as 259364. Marking as duplicate as we will do work there.
