[Problem/Bug]: SourceBuffer.changeType always fails with Edge 130 on Xbox

What happened?

On Xbox, when using SourceBuffer.changeType to pass a new h264 codec profile, an error is always thrown mentioning the codec is not supported:

Failed to execute 'changeType' on 'SourceBuffer': Changing to the type provided ('video/mp4; codecs="avc1.xxx"') is not supported.

This does occur on Xbox using WebView2 with Edge v130, but cannot be reproduced when using a Chrome or Edge browser, or WebView2 with Edge v131 on a desktop.

Importance

Moderate. My app's user experience is affected, but still usable.

Repro steps

When running this script. Any h264 codec profile being passed on changeType fails:

  if (window.MediaSource) {
    logMessage('Media Source Extensions are supported.');
    const video = document.getElementById('video');
    const mediaSource = new MediaSource();
    video.src = URL.createObjectURL(mediaSource);
    mediaSource.addEventListener('sourceopen', () => {
      logMessage('MediaSource is open.');
      try {
        const sourceBuffer = mediaSource.addSourceBuffer('video/mp4; codecs="avc1.4d0028"');
        logMessage('SourceBuffer created with initial type: avc1.4d0028.');
        sourceBuffer.changeType('video/mp4; codecs="avc1.4d001f"');
        logMessage('SourceBuffer type changed to: avc1.4d001f.');
      } catch (error) {
        logMessage(`Error changing SourceBuffer type: ${error.message}`);
      }
    });
  } else {
    logMessage('Media Source Extensions are not supported in this browser.');
  }
