Description

On  Android 9.0 tablet trying to share the screen return an error

navigator.mediadevice.getDisplayMedia is not a function

That's an expected behavior when the browser/OS does not support screensharing

The unexpected Result:

1. The screen sharing dialog has a disabled Stop button
2. New participants see an empty "shared screen" with the user picture.
3. No one can share his screen until the tablet makes a refresh of his browser window

Seems that an error starting the screen sharing does not stop the already started sharing connection.
