Re: [webrtc-pc] mDNS ICE trips Local Network permission prompt on macOS (#3109)

> And a fiddle merely emitting `.local` candidates does not trigger? That would suggest it is triggered by the attempt to do a MDNS resolution. You might want to grab a sysdiagnose for [@youennf](https://github.com/youennf)

It isn't an mDNS resolution that is triggering this. Gathering an mDNS candidate means that the hostname must be *broadcast* to the local network (see https://datatracker.ietf.org/doc/html/rfc6762#section-8.1). No other peer connection needs to exist for this to happen. So, if there's an OS-level permission on whether this kind of broadcast is allowed, it's going to pop up.
