Getting devices from webrtc always returns different ids

Hi,

I have a problem when using method 'navigator.mediaDevices.enumerateDevices()' to get list of the available media input and output devices.
Everytime the WebEngine is closed, the list of devices retrieved in the next execution, has different ids; I expect that ids remain the same.

This is documentation of this feature: https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices/enumerateDevices

Thanks.
