title: How to fully close a WebRTC connection
body: <p>When I am trying to close the WebRTC connection after a call using rtc.close(), I recognize that about:webrtc-internals in Chrome and about:webrtc keep the connections listed. In Firefox, they are marked as closed, while in Chrome I could not see such a denotation.</p>
  
  <p>I am asking because this seems to have a significant performance impact after some time. After having done a lot of calls, the performance is significantly impaired and webrtc-internals lists a large number of connections.</p>
  
  <p>Is there anything more to closing a WebRTC connection than .close() to make the browser fully forget about the connection?</p>
