AssertConfigurationIsValid succeeds when ReverseMap from a record to a class constructed using ForCtorParam

[tsvx]

Source/destination types

public class INodeSettings
{
    public string IP { get; set; }
    public string Login { get; set; }
    public string Password { get; set; }
    public int RelayIndex { get; set; }
    public bool InvertSignal { get; set; }
}

public record INodePowerLine(
    string EndPoint,
    string Login,
    string Password,
    int RelayIndex,
    bool Inverted
);

Mapping configuration

CreateMap<INodeSettings, INodePowerLine>()
      .ForCtorParam(nameof(INodePowerLine.EndPoint), opt => opt.MapFrom(s => s.IP))
      .ForCtorParam(nameof(INodePowerLine.Inverted), opt => opt.MapFrom(s => s.InvertSignal))
      .ReverseMap();

Version: 13.0.1

Expected behavior

config.AssertConfigurationIsValid() should throw an exception because the reverse mapping (from INodePowerLine to INodeSettings) is invalid -- the fields IP and InvertSignal got default values anyway.

Actual behavior

Steps to reproduce

Test:

var config = new MapperConfiguration(cfg =>
{
    cfg.AddProfile<DefaultProfile>();
});
config.AssertConfigurationIsValid();

Prove that the reverse mapping from INodePowerLine to INodeSettings is invalid -- the fields IP and InvertSignal got default values:

	var mapper = config.CreateMapper();

	var settings = new INodeSettings
	{
		IP = "192.168.1.23:50",
		Login = "admin",
		Password = "pass",
		RelayIndex = 14,
		InvertSignal = true
	};
	settings.Dump();

	var powerLine = mapper.Map<INodePowerLine>(settings);
	powerLine.Dump();

	var settings2 = mapper.Map<INodeSettings>(powerLine);
	settings2.Dump();

Oh, thank you. Just found the defaults for ReverseMap() in the docs.
