Most of it looks good to me, but we may have an issue with returning the `scalabilityMode` of the preferred codec before negotiation as it may change if we call `setCodecPreferences()` and we could unintentionally change the meaning from "use default value" to "use a specified value".

How can we make sure that the default value is preserved for applications that aren't aware of the SVC specification and yet use `setParameters()` and `setCodecPreferences()`?
Should we also invalidate the `sender.[[LastReturnedParameters]]` internal slot after calling `setCodecPreferences()`?
