[Bug 18515] Provide more details on behavior of the media element when the key for an encrypted block is not available

https://www.w3.org/Bugs/Public/show_bug.cgi?id=18515

--- Comment #15 from Adrian Bateman [MSFT] <adrianba@microsoft.com> ---
Discussed status in the telcon 12/17:

* We have previously decided not to update the media element readyState when
blocked waiting for a key because this would, for example, adversely impact
other code dependent on readyState such as adaptive rate switching with MSE.

* We do want applications to have a way to detect the state where playback is
blocked waiting for a key in order to update their UI to indicate waiting.

* One possible solution is to use the HTML5 waiting event for this purpose and
to extended the media element with a waitingReason attribute that could
indicate whether the waiting event is for network issues or EME or something
else (in future).

Jerry and I are still discussing possibilities here and Jerry has the next
action to update this bug.
