GetAuthenticationStateAsync isn't invoked when navigating using enhanced navigation

[grallbring]

Is there an existing issue for this?

• I have searched the existing issues

Describe the bug

When navigating within my .NET 9 Blazor Server application, GetAuthenticationStateAsync of my custom AuthenticationStateProvider isn't invoked. I think my issue is related to #39929, where the conclusion was to "perform a check inside AuthenticationStateProvider" by @javiercn, which, as I understand it, I am doing and since this isn't working this might be a bug.

Expected Behavior

When navigating the Blazor Server application using links it should invoke GetAuthenticationStateAsync so I can verify that the user's session is still valid.

Steps To Reproduce

• Add a custom AuthenticationStateProvider to the project.
• GetAuthenticationStateAsync is invoked when the user first visits the application or triggers a hard reload.
• GetAuthenticationStateAsync is not invoked when clicking a link, thus using enhanced navigation.
