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 ran on the server, isAdmin is true when my logged-in user is 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?
