A substitute on Type instance not recognized in a method call setup

[Prologh]

Describe the bug
A substitute on Type instance seems to be not recognized properly when used to setup method call.

To Reproduce

Interface:

public interface ITypeFormatter
{
    string GetPrettyTypeName(Type type);
}

Test code:

var typeMock = Substitute.For<Type>();
var typeFormatterMock = Substitute.For<ITypeFormatter>();
typeFormatterMock
    .GetPrettyTypeName(typeMock)
    .Returns("pretty name");
var result = typeFormatterMock.GetPrettyTypeName(typeMock);

Debug.Assert(!string.IsNullOrEmpty(result), "Result should not be null or empty.");

Expected behaviour
I would expect for result variable to not be empty and it's value be exactly pretty name just the way I configured the call.

When I use Arg.Any<Type>() instead of typeMock in call setup, it works.

Using Arg.Is(typeMock) does not help.

Environment:

• NSubstitute version: 5.3.0
• Platform: .NET 8.0 project on Windows
