Review mute/unmute/ended and constraints on tracks from canvas.captureStream()

[jan-ivar]

As per w3c/mediacapture-main#984, review mute/unmute/ended and constraints on tracks from canvas.captureStream().

canvas.captureStream only mentions mute once (though would ended be more appropriate, or does a dirty canvas get cleaned?):

It doesn't say anything about ended or unmute. It should clarify if events are fired. No mention of constraints.

Relevant open issues found:
