unbindVideoElement API does not remove MediaStream

[p-foucht]

Describe the bug
The unbindVideoElement API does not remove the MediaStream from the video element. Since the bindVideoElement is responsible for attaching the stream, the unbindVideoElement call should remove it.

This is needed when moving video elements around the DOM. Currently, unbinding and rebinding the same VideoTile will create two videos playing the same stream.

Workaround
You can workaround this by manually remove the srcObject of the video element, or disposing of the video element altogether.

const videoEl = document.querySelector(...);
audioVideo.unbindVideoElement(3);
videoEl.srcObject = null;

Fix
To not break backwards compatability, allow passing some optional config when calling unbindVideoElement that will detach the MediaStream.

We want to invlude this change in the next major version update - it would be a breaking change to the current api definition.
