Should AuthorizeView care whether IIdentity.IsAuthenticated?

To better understand how authentication works in Blazor, I'm playing around with a minimal implementation of AuthenticationStateProvider. As expected, if I implement GetAuthenticationStateAsync() like this, an AuthorizeView displays the not-authorized content:

public override Task<AuthenticationState> GetAuthenticationStateAsync() =>    Task.FromResult(new AuthenticationState(new ClaimsPrincipal())); // 👈 no identity

And if I implement it like this, an AuthorizeView displays the authorized content:

public override Task<AuthenticationState> GetAuthenticationStateAsync() =>    Task.FromResult(new AuthenticationState(new ClaimsPrincipal(new DummyIdentity())));

private class DummyIdentity : IIdentity{    public string? AuthenticationType => "Dummy";    public bool IsAuthenticated => true;    public string? Name => "Anonymous";}

But if I change DummyIdentity.IsAuthenticated to false, I still see the authorized content. What actually matters is AuthenticationType. If it's is null or empty, it's unauthorized. If it's any non-empty string, including whitespace, it's authorized. Is this the expected behavior?
