Warning not thrown for source nested property with no mapping

[ShahryarSaljoughi]

Describe the bug
I expect to see a warning if a property from the source of mapping is not mapped to anything.
Here is my mapping declaration:

[MapProperty(
     source: nameof(VoucherCreationRequest.CustomersConditions),
     target: nameof(@VoucherDefinition.CriteriaContainer.CustomerPropertiesCriteria))]
public static partial void PatchInternal(this VoucherCreationRequest source, VoucherDefinition destination);

public static partial CustomerPropertiesCriteria MapCustomerConditionsDtoToCriteria(this CustomersConditionsDto source);

And these are the types of source and destination:

public class VoucherCreationRequest
{
    public VoucherBranchCriteriaDto? BranchCriteria { get; set; }
    public MinimumInvoicePriceCriteriaDto? MinimumInvoicePriceCriteria { get; set; }
    public CustomersConditionsDto CustomersConditions { get; set; } = new ();
}

public abstract class VoucherDefinition
{
    public CriteriaContainer? CriteriaContainer { get; set; } = new();
}

public class CriteriaContainer: IDbEntity
{
    public MinimumInvoicePriceCriteria? MinimumInvoicePriceCriteria { get; set; }
    public VoucherBranchCriteria? VoucherBranchCriteria { get; set; }
    public CustomerPropertiesCriteria? CustomerPropertiesCriteria { get; set; }

    // This one is not mapped
    public CustomerCalendarBasedCriteria? CustomerCalendarBasedCriterionData { get; set; }

}

public class CustomersConditionsDto: CustomersFilterDto
{
    public DateTimeOffset? FromSpouseBirthDateTime { get; set; }
    public DateTimeOffset? ToSpouseBirthDateTime { get; set; }
}

public class CustomersFilterDto
{
    ...
    public PartialDateFilter? PartialBirthDateFilter { get; set; }
    public PartialDateFilter? PartialMarriageDateFilter { get; set; }
    public PartialDateFilter? PartialSpouseBirthDateFilter { get; set; }
}

I want to map VoucherCreationRequest.CustomersConditions to VoucherDefinition.CriteriaContainer.CustomerPropertiesCriteria and also I want to map from the same ``VoucherCreationRequest.CustomersConditionstoVoucherDefinition.CriteriaContainer.CustomerCalendarBasedCriterionData`.
Nothing is mapped to `VoucherDefinition.CriteriaContainer.CustomerCalendarBasedCriteria`. Hence some warning regarding that is supposed to be thrown but currently is not.

The only relevant warning I get is about the PartialBirthDateFilter property on source not being mapped to any member on CustomerPropertiesCriteria. Nothing is warned about CustomerCalendarBasedCriteria.

The main reason for me to use Mapperly, is the warnings that help prevent any piece of data being lost during conversions by mistake. So we really need those warnings to appear.
