Registering a new WebAuthn Credential on Safari 15.4 on Intel MacBooks always results in a "NotAllowedError: This request has been cancelled by the user.".

Credentials are being created using the following (example) code:

navigator.credentials.create({"publicKey":{"authenticatorSelection":{"userVerification":"preferred"},"attestation":"none","excludeCredentials":[],"challenge":{"0":60,"1":105,"2":99,"3":48,"4":46,"5":97,"6":112,"7":112,"8":62},"pubKeyCredParams":[{"type":"public-key","alg":-7},{"type":"public-key","alg":-257}],"rp":{"name":"Internet Identity Service"},"user":{"id":{"0":233,"1":93,"2":39,"3":244,"4":156,"5":154,"6":167,"7":102,"8":29,"9":152,"10":233,"11":59,"12":187,"13":89,"14":192,"15":131},"name":"Internet Identity","displayName":"Internet Identity"}}})
