        Attempting to load captions during the license exchange causes an error.

         

        ```

        <video src="fairplay.m3u8">

             <track kind="captions" label="English" srclang="en" src="test.vtt" />

        </video>

        ```

        It looks like if you programmatically add `TextTrack` on `document.getElementsByTagName('video')[0].addEventListener('firstplay')` the error doesn't occur.

         

        I have verified that this error only occurs when you try and side load captions of encrypted content.

         

        Looking for more information surrounding the problem/capabilities.

         

        Regards,
