recordingStarted event is not fired after using "record again" button

[h-unterp]

Using <script src="https://www.kaltura.com/apps/expressrecorder/latest/express-recorder.js"></script>
and

 expRec.instance.addEventListener("recordingStarted", function () {
                console.log("STARTED");

Steps to reproduce:

1. Use red recording button.
2. Record for a few second
3. Stop recording
4. Use "record again button"
5. Observe that recordingStarted is not fired
6. recordingEnded does fire correctly throughout all steps.
