Flattened properties via IncludeMembers don't get mapped correctly in expressions

This time I think this issue is related to this library.
I have a model and dtos like this:
```csharp
public class Category{
  [...]
  
  public string? Name {get; set;}
}

public class Product{
  [...]
  
  public Category? Category {get; set;}
}


public class ProductDTO{
  [...]
  
  public string? CategoryName {get; set;}
}
```

If I create the maps "manually", everything works:
```csharp
CreateMap<Product, ProductDTO>()
  [...]
  .ForMember(p => p.CategoryName, c => c.MapFrom(p => p.Category!.Name));
```

I can then query it regularly:
```csharp
Db.Products!.UseAsDataSource(_mapper.ConfigurationProvider).For<ProductDTO>()
  .FirstOrDefault(p => p.CategoryName == "MyCategory");
```

But if I try to include the Category entity:
```csharp
CreateMap<Category, ProductDTO>()
  [...]
  .ForMember(p => p.CategoryName, c => c.MapFrom(c => c.Name));

CreateMap<Product, ProductDTO>()
  [...]
  .IncludeMembers(p => p.Category);
```

Then I get an exception in the query:
```
'Property 'String CategoryName' is not defined for type '[...].Product' Arg_ParamName_Name'
```

Here's the full stack trace:
