Thank You for implementing the MediaRecorder.start(timeslice) parameter!

We developed a test to verify the MediaRecorderOptions parameter & mimeType property @ https://codepen.io/XachMoreno/full/bGpXdXX.

The MediaRecorderOptions.mimeType property within the MediaRecorder constructor is being ignored & the MIME type is fixed as video/mp4.

Furthermore, the MediaRecorder.isTypeSupported method is not implemented.

To replicate...

 1. Open Safari 14 or Safari Technology Preview 14.0.1
 2. Open the Develop Menu
 3. Hover over the Experimental Features list item
 4. Click on MediaRecorder to Enable it
 5. Navigate to https://codepen.io/XachMoreno/full/bGpXdXX
 6. Click on the red Request Media Permissions button at the bottom
 7. Allow access to Microphone & Camera
 8. Click on the Test Media Recorder Options button at the bottom
 9. Wait 1 seconds
 10. An alert dialog will open communicating test results for
     1. the MediaRecorder.mimeType property
     2. the MediaRecorder.isTypeSupported method
     3. MediaRecorderOptions.mimeType vs. MediaRecorder.mimeType
     4. MediaRecorderOptions.mimeType vs. Blob.type
