reproduction example

If a .m3u8 file is set a src on an audio element the manifest plays correctly. If you put that exact same manifest inline and set it as src as a data url e.g. `data:application/vnd.apple.mpegurl;base64,<encoded manifest>}` then a stalled event is fired and nothing plays.

Attached repro includes some additional details and examples of playing with both encrypted/clear content and using both url and data url.
