Re: [webauthn] UAs can't pass unknown extensions to authenticators

Yes, https://tools.ietf.org/html/rfc7049#section-4.2 plus applying our canonicalization rules is what is expected. You're right that if floating point is present, our canonicalization can't be performed, in which case, that extension would be dropped.  We can say those things explicitly if would make things clearer.
