Filed https://github.com/w3c/mediacapture-screen-share/issues/136.
Leaving it as defect for now since Chrome does this.

Reproduced issue at Nightly 78. Neither closing captured screen or window nor executing stop() results in ended event being fired.
When stop() is executed ended attribute is set to true.
If the captured screen or window is simply closed track.readyState value is still "live" and track.muted value is false. How is that possible?

The spec issue in comment 1 has been closed, since the spec is already clear we should be firing the ended event here.

The severity field for this bug is relatively low, S3. However, the bug has 3 duplicates.
:jib, could you consider increasing the bug severity?

In DesktopCapture, the callback OnCaptureResult also returns a result of
CaptureFrame, whether it was successful or failed. When ERROR_PERMANENT
is returned, it means that all the following attempts to capture a frame
will not succeed and at this point we should stop capturing. To stop
capturing, we propagate CaptureEnded event up to the DeviceListener and
stop screencast.

This is a simple backport of an WebRTC upstream change.
