In 52 this fails as described above but in nightly this seems to work. Nils, do you know if 831926 was resolved in another bug?

No none of the code around that has changed.

But you might have tested different scenario. Here is what I found:

- without e10s I always get the network state error
- with e10s:
  - if I first select "work offline" and then open the console to paste the code I get no error
  - if I first open the console, then select "work offline" and then paste the code I get again the error

So not getting the error message is basically some kind of bug in the code which currently still prevents you from using PeerConnections w/o network.

I think this is basically a dupe of bug 831926.
