[mediacapture-fromelement] Expand on captureStream() for CORS-cross-origin media data

foolip has just created a new issue for 
https://github.com/w3c/mediacapture-fromelement:

== Expand on captureStream() for CORS-cross-origin media data ==
The description of 
[`captureStream()`](http://w3c.github.io/mediacapture-fromelement/#widl-HTMLMediaElement-captureStream-MediaStream)
 talks about "The contents of the track might become inaccessible to 
the current origin due to cross-origin protections." AFAICT it says 
nothing normative, and what is said is not specific enough to write 
cross-browser tests for.

The HTML spec doesn't have any per-track notion of cross-origin, it's 
the entire media element that's either CORS-same-origin or not. If a 
per-track notion is required by this spec, we need to talk about how 
to expose that on the `AudioTrack` and `VideoTrack` objects.
