How to listen for Stop sharing click in Chrome DesktopCapture API

I'm currently writing a chrome extension which uses Chrome's DesktopCapture API. I'm struggling to set a callback when someone clicks on Stop sharing.

Stop

I tried using the onended EventHandler of the MediaStream, but the MediaStream's ended property is still set to true after clicking on the button.

The only difference I could find between the stream (before and after clicking the button) is that the videoTracks.readyState is set to ended.

Edit:
I would also like to notice if the user closes the window they were streaming before.

I solved this issue by assigning an EventHandler on the videoTrack's onended property:

  // somebody clicked on Stop sharing

  stream.getVideoTracks()[0].onended = function () {

    // doWhatYouNeedToDo();

  };

As far as my edit goes (noticing a closing window): it also fires the event.
