Description Philipp Hancke 2019-06-15 03:06:56 PDT 
from https://stackoverflow.com/questions/56606608/is-safaris-rtcdatachannel-implementation-completely-broken

Simplified steps to reproduce:
On a site without getUserMedia permission, paste this:
```
const pc = new RTCPeerConnection();
pc.onicecandidate = (e) => console.log(e.candidate)
pc.onicegatheringstatechange = () => {
  if (pc.iceGatheringState === 'complete') {
    console.log(pc.localDescription.sdp);
  }
};
pc.createDataChannel("aint-broken");
pc.createOffer().then(offer => pc.setLocalDescription(offer.sdp));
```
Note that the onicecandidate events shows mdns host candidates but pc.localDescription.sdp does not contain any candidate.

err... bug in the repro script:
  pc.setLocalDescription(offer)
not
  pc.setLocalDescription(offer.sdp)

Thanks for the report.
I am not sure this should be a real issue in practice.
But we should get there at some point though.
