The capture tab stream will be sent over a local peerconnection and rendered back, displaying the stats for the stream:

{
  "frameWidth": 316,
  "frameHeight": 180,
  "framesPerSecond": 31,
  "qualityLimitationReason": "bandwidth",
  "qualityLimitationDurations": {
    "other": 0,
    "cpu": 0,
    "bandwidth": 9979,
    "none": 29
  },
  "qualityLimitationResolutionChanges": 0,
  "encoderImplementation": "libvpx",
  "firCount": 0,
  "pliCount": 0,
  }

If you click "play" on the tab a youtube will be played, but the stream is still at 180P

If you click on "replace track" to replace the track on the rtp sender with the same track object, the stream is received at 720P
