cloned_track_issue_sample

Environment:
- iPadOS 17.0 (21A5326a)
- iOS 17.0


We noticed strange issue when sending cloned track via peer connection - cloned track has another resolution.

To reproduce this:
- get user media with constraints ({ video: { width: 640, height: 360 } })
- clone video track
- add this track to peer connection
Actual result: 
- track is send with resolution 960x540 (instead of 640x360)
Expected result:
- resolution should be the same as in the original track (640x360)

I create little sample to try this issue.
