Re: [webauthn] Clarify 127.0.0.1 in spec (#1204)

> Let's go with this example. Assume that there is a web page hosted at 127.0.0.1 and it serves up a self-signed cert with foo.google.com.

Ok:
   * DNS for foo.google.com resolves to 127.0.0.1
   * Server on 127.0.0.1:443 serves self-signed certificate for foo.google.com
   * User enters `https://foo.google.com`, browser loads from local server.
   * User presumably overrides the certificate error.

Then yes, that Javascript can exercise the RP ID `google.com`.

But your proposal was:
> All domain names that resolve to 127.0.0.1 should have the same RP ID

But here, `foo.google.com` is a domain name that resolves to 127.0.0.1, but it doesn't have the same RP ID as all others domains that resolve to 127.0.0.1.
