.NET 8 Blazor - Navigation - AuthenticationStateProvider Bug

Is there an existing issue for this?

Describe the bug

A very interesting issue. I have a NavMenu that loads dynamic NavItems. I built a nice template and created the following element for subitems:

<li class="mb-1 mt-1">
    <NavLink href="@subItem.Route" class="link-body-emphasis d-inline-flex text-decoration-none rounded fs-6">
        <span>@subItem.Name</span>
    </NavLink>
</li>

In the past few days, I was desperately trying to figure out why client-side rendered components were behaving strangely. As long as a NavItem had no subitems, my UserService, which accesses the AuthenticationStateProvider, worked without any issues. However, when I navigated using a subitem, the AuthenticationState was always "Unauthenticated". After removing any potential sources of error from the components (the components are, in this case, pages), the only remaining possible issue was the navigation. Interestingly, the AuthState was correctly loaded when I navigated directly via the browser link.

The issue can easily be resolved by embedding an HTML element in the @subItem.Name. But so the enhanced navigation wont work anymore. So maybe this is the problem.

Update:
Its definitive caused by enhanced navigation, if you set data-enhance-nav="false" the problem is gone, but the navbar always reloads...

<li class="mb-1 mt-1">
    <NavLink href="@subItem.Route" class="link-body-emphasis d-inline-flex text-decoration-none rounded fs-6">
        <a>@subItem.Name</a>
    </NavLink>
</li>

Expected Behavior

AuthenticationStateProvider returns IsAuthenticated = false

Steps To Reproduce

Navigate with this NavLink:

<li class="mb-1 mt-1">
    <NavLink href="@subItem.Route" class="link-body-emphasis d-inline-flex text-decoration-none rounded fs-6">
        @subItem.Name
    </NavLink>
</li>

Exceptions (if any)

IsAuthenticated = false

.NET Version

8.0.400

Anything else?

The problem also occurs, if you simply use the <a> Tag. So its not based on the <NavLink />
