Re: [webauthn] registration of EdDSA credentials without resident keys fails (#1437)

In this case it's about the RP not supporting ES256. Currently Chrome is routing the request to the U2F stack because a PIN is set on the authenticator but then the U2F stack is dropping it because it cannot be translated without ES256 support. In this corner-case, I think Chrome could behave better.

Chrome can't do that without changes to the authenticator, but those changes are ready in the next version of CTAP2, so that should be the case in the future.
