Re: [webauthn] Cross origin authentication without iframes (accommodating SPC in WebAuthn) (#1667)

> Not a problem if there is always an allow list.

The SPC spec currently requires an `allowList` ([we called it credentialIds](https://w3c.github.io/secure-payment-confirmation/#dom-securepaymentconfirmationrequest-credentialids)), so the short term seems ok.

Thinking long term - my gut feel is that 'we' (everyone) wouldn't want discoverable credentials to work cross-origin as it feels even more dicey security/privacy wise; but I may be wrong.
