Describe the bug

Moving Minimal APIs handler with single param of type HttpContext results in empty response.

WebApplicationBuilder builder = WebApplication.CreateBuilder();
WebApplication app = builder.Build();
app.Map("/Fails", Fails);
app.Map("/Fails1", Fails1);
app.Map("/Works", async (HttpContext c) =>
{
    var response = await Task.Run(() => { return "response"; });
    return response;
});
// /WorksToo?someParam=1
app.Map("/WorksToo", Works);
app.Map("/WorksToo1", Works1);
app.Map("/WorksToo2", Works2);
app.Run();
static async Task<string> Fails1(HttpContext context)
{
    var response = await Task.FromResult("response");
    return response;
}
public partial class Program
{
    internal static async Task<string> Fails(HttpContext context) => await Task.FromResult("response");

    internal static async Task<string> Works(HttpContext context, string someParam) => await Task.FromResult("response");

    internal static async Task<string> Works1(HttpContext context, ILogger<Program> _) => await Task.FromResult("response");

    internal static async Task<string> Works2(HttpRequest context) => await Task.FromResult("response");
}

Endpoints named Fails return empty result (chrome, postman, no Content-Type) while others result in response (Content-Type: text/plain; charset=utf-8")

Expected Behavior

All returns the same - response.

Steps To Reproduce

Run the app in the description and call endpoints.

Exceptions (if any)

No response
