DoNotValidate error when property name is the same between two objects

[nathan-newman6519]

Using the DoNotValidate on a source member, causes problems when the dest member has a property with the same name that is mapped to a different property. An example of this issue is below along with a possible workaround. Should both of these be equivalent?

    [Fact]
    public void DoesNotWork_DestModelWithUnmappedSourceModel()
    {
        var config = new MapperConfiguration(_ => _.CreateMap<SourceModel, DestModel>()
            .ForMember(src => src.Id, dest => dest.MapFrom(_ => _.SystemId))
            .ForMember(src => src.Name, dest => dest.MapFrom(_ => _.Name))
            .ForSourceMember(src => src.Id, opt => opt.DoNotValidate())
            .ReverseMap()
        );
        var mapper = config.CreateMapper();
        var destination = new DestModel()
        {
            Id = "Test",
            Name = "TestName"
        };
        var source = mapper.Map<SourceModel>(destination);
    }
    
    [Fact]
    public void Works_DestModelWithUnmappedSourceModel()
    {
        var config = new MapperConfiguration(_ => _.CreateMap<DestModel, SourceModel>()
            .ForMember(src => src.SystemId, dest => dest.MapFrom(_ => _.Id))
            .ForMember(src => src.Name, dest => dest.MapFrom(_ => _.Name))
            .ForMember(src => src.Id, opt => opt.Ignore())
            .ReverseMap()
        );
        var mapper = config.CreateMapper();
        var destination = new DestModel()
        {
            Id = "Test",
            Name = "TestName"
        };
        var source = mapper.Map<SourceModel>(destination);
    }

    
    public class DestModel
    {
        public string Id { get; set; }
        public string Name { get; set; }
    }

    public class SourceModel
    {
        public Guid Id { get; set; }
        public string SystemId { get; set; }
        public string Name { get; set; }
    }
