AuthenticationStateProvider propagates incomplete identity to WebAssembly with Blazor in .NET 8

I have a component using auto render mode:

@attribute [RenderModeInteractiveAuto]

I inject the AuthenticationStateProvider:

@inject Microsoft.AspNetCore.Components.Authorization.AuthenticationStateProvider _auth

Now, in my code, if I do something like this:

var state = await _auth.GetAuthenticationStateAsync();var user = state.User;var isAdmin = user.IsInRole("admin");

When this is run on the server, isAdmin is true for logged-in users in the admin role. However, on WASM, this is false. Plus, on the server side, the name claim correctly contains the user name whereas in WASM it contains the e-mail address.

Is this still a bug, or do I have to tweak some settings to get the correct identity propagated?
