User Profile

Safari is allowing users to create multiple passkeys despite setting the excludeCredentials in PublicKeyCredentialCreationOptions (https://developer.mozilla.org/en-US/docs/Web/API/CredentialsContainer/create#excludecredentials). I also included appidExclude(https://developer.mozilla.org/en-US/docs/Web/API/Web_Authentication_API/WebAuthn_extensions#appidexclude) but it was still allowing me to create multiple passkeys on the same iCloud account. This does not happen in other browsers. Can anyone point me to any documentation regarding this? Much appreciated https://developer.mozilla.org/en-US/docs/Web/API/Web_Authentication_API/WebAuthn_extensions#appidexclude https://developer.mozilla.org/en-US/docs/Web/API/CredentialsContainer/create#excludecredentials
