When FaceID and passcode are turned off, PublicKeyCredential.isUserVerifyingPlatformAuthenticatorAvailable resolves to true, but registration of platform authenticator fails

Hi there!

I'm using PublicKeyCredential.isUserVerifyingPlatformAuthenticatorAvailable to detect whether a platform authenticator is available in order to prompt to register it. On iOS 16 it resolves to true even when FaceID and passcode are turned off in system settings. In this case, when navigator.credentials.create is called with "authenticatorAttachment" set to "platform", it immediately fails with the following error, without showing any UI

{
	code: 0,
	message: "This request has been cancelled by the user.",
	name: "NotAllowedError"
}

To me, one of these functions does not work correctly, so I am wondering which one is it?

I assume that on iOS 16 PublicKeyCredential.isUserVerifyingPlatformAuthenticatorAvailable resolves to true because it should be possible to register a passkey on another device. But in that case navigator.credentials.create would suggest to do that instead of failing, right?

Thanks in advance for any help.
