Hiding Method in Derived Interface Generates Invalid Code

[JasonBock]

To Reproduce

var code =
  """
  using Rocks;
  
  [assembly: Rock(typeof(IServiceDerived), BuildType.Create | BuildType.Make)]
  
  public interface IOutBase { }
  
  public interface IOutDerived : IOutBase { }
  
  public interface IServiceBase
  {
    void TryGet<T>(out T value) where T : IOutBase;
  }
  
  public interface IServiceDerived : IServiceBase
  {
    new void TryGet<T>(out T value) where T : IOutDerived;
  }
  """;

Expected behavior

Mock code is generated with errors.

Actual behavior
The following error occurs:

// Rocks\Rocks.RockGenerator\IServiceDerived_Rock_Create.g.cs(49,15): error CS0425: 
The constraints for type parameter 'T' of method 'IServiceDerivedCreateExpectations.Mock.TryGet<T>(out T)' must match the constraints for type parameter 'T' of interface method 'IServiceBase.TryGet<T>(out T)'. Consider using an explicit interface implementation instead.

Additional context

This can be fixed if the base type is generated explicitly:

public class SD : IServiceDerived
{
  public void TryGet<T>(out T value) where T : IOutDerived
  {
    throw new NotImplementedException();
  }

  void IServiceBase.TryGet<T>(out T value)
  {
    throw new NotImplementedException();
  }
}
