Why is the Home Controller's Index action not being hit when program starts up?

Question

When I start my ASP.NET MVC application up, it does not hit the HomeController's Index action, but when I explicitly type the URL Home/Index, it works as expected.

Here is how the end point is set up in Startup.cs:

app.UseEndpoints(endpoints =>
        {
            // endpoints.MapControllers();
            endpoints.MapControllerRoute("default", "{controller=Home}/{action=Index}/{id?}");

            // Blazor
            endpoints.MapFallbackToPage("/_Host");
            endpoints.MapBlazorHub();
        });

@page "/"

into

@page ""
