Service is registered twice

[CoenraadS]

When I try to register a scoped service, it seems the interface is registered as scoped, but the concrete class is also registered as transient?

using Microsoft.Extensions.DependencyInjection;
using System.Linq;
using Xunit;

namespace Scrutor.Tests;

public class RegistrationTest : TestBase
{
    private IServiceCollection Collection { get; } = new ServiceCollection();

    [Fact]
    public void ShouldRegisterOnce()
    {
        Collection.Scan(scan => scan
            .FromTypes(typeof(MyClass))
            .AddClasses(classes => classes.AssignableTo<MyInterface>())
            .As<MyInterface>()
            .WithScopedLifetime());

        Assert.Single(Collection);
    }
}

public interface MyInterface
{
}

public class MyClass : MyInterface
{
}

Message: 
Assert.Single() Failure: The collection contained 2 items
Collection: [ServiceType: Scrutor.Tests.MyClass Lifetime: Transient ImplementationType: Scrutor.Tests.MyClass, ServiceType: Scrutor.Tests.MyInterface Lifetime: Scoped ImplementationType: Scrutor.Tests.MyClass]
