Blazor Web Individual Account Template does not have the Logout form handler

Issue #51134 replace the LogoutForm into a standard post form. This can fix the problem that the LogoutForm won't work when nested in Interactive RenderMode, since it needs the HttpContext. The standard post form needs a form handler, but I did not find the endpoint definition of Account/Logout. Thre will be no handler for the logout form. If I get something wrong?

- <LogoutForm id="logout-form" />
- <NavLink class="nav-link" href="#" onclick="document.getElementById('logout-form').submit(); return false;">
-     <span class="bi bi-arrow-bar-left-nav-menu" aria-hidden="true"></span> Logout
- </NavLink>
+ <form action="Account/Logout" method="post">
+   <AntiforgeryToken />
+     <input type="hidden" name="ReturnUrl" value="@currentUrl" />
+     <button type="submit" class="nav-link">
+         <span class="bi bi-arrow-bar-left-nav-menu" aria-hidden="true"></span> Logout
+     </button>
+ </form>

Describe the solution you'd like

Add the needed form handler if there is something wrong. If not, point out the existing handler code location.

The logout endpoint is defined using MapPost (Minimal APIs) in IdentityComponentsEndpointRouteBuilderExtensions along with a few other endpoints that support the Identity Razor components.

	ClaimsPrincipal user,
	SignInManager<ApplicationUser> signInManager,
	[FromForm] string returnUrl) =>
	{
	await signInManager.SignOutAsync();
	return TypedResults.LocalRedirect($"~/{returnUrl}");
