Comment (by cohosh):

 Replying to [comment:3 dcf]:
 > In Firefox, go to `about:networking#sockets` and see if the open sockets
 are listed there. Is it clear what they are used for / related to? I
 suppose it can only be ICE related.

 I think your intuition here was correct. Calling `close()` for the
 PeerConnection terminates ICE and releases these resources:
