[Bug]: BodySerializationMethod.UrlEncoded with Complex view model class

[infofromca]

Describe the bug 🐞

I have a very complex class called CheckoutViewModel:
using OrchardCore.Commerce.MoneyDataType;
using System.Collections.Generic;

namespace OrchardCore.Commerce.Payment.ViewModels;

public class CheckoutViewModel : PaymentViewModel //, ICheckoutViewModel
{
    public string? ShoppingCartId { get; set; }

    public Amount GrossTotal { get; set; } = new();

    // [BindNever]
  //  public IEnumerable<OrchardCore.Commerce.Abstraction.ViewModels.Region> Regions { get; set; } = Array.Empty<OrchardCore.Commerce.Abstraction.ViewModels.Region>();

   // [BindNever]
    public IDictionary<string, IDictionary<string, string>> Provinces { get; set; } =
        new Dictionary<string, IDictionary<string, string>>();

    public string? UserEmail { get; set; }

    public bool IsInvalid { get; set; }

  //  public IEnumerable<IShape> CheckoutShapes { get; set; } = Array.Empty<IShape>();

    //public CheckoutViewModel(OrderPart orderPart, Amount singleCurrencyTotal, Amount netTotal)
    //    : base(orderPart, singleCurrencyTotal, netTotal) =>
    //    Metadata.Type = "Checkout";

    //public CheckoutViewModel()
    //    : base() =>
    //    Metadata.Type = "Checkout";
}

Step to reproduce

[Post("/api/checkout/confirm/{providerName}/{paymentIntentId}/{shoppingCartId}?middleUrl={middleUrl}")]
Task ConfirmPaymentAsync(
string providerName,
string paymentIntentId,
string shoppingCartId,
string middleUrl,
[Body(BodySerializationMethod.UrlEncoded)] CheckoutViewModel checkoutViewModel,
CancellationToken cancellationToken = default);
2. Click on submit to have a http post aync calling to api server
3. Scroll down to it hit the api server which is ok .
4. See error
but I got this 👍 POST /api/checkout/confirm/Stripe/pi_3PsrfnRpyWVeDn6H0MxBWbGo_secret_r7Q8wEngIEPH0JeVjLzfuCECs/4hap81e272txkszm6jrryh52xj?middleUrl=guangmauiauth HTTP/1.1
Host: localhost:62354
Content-Type: application/x-www-form-urlencoded
Content-Length: 544

RegionList=System.Collections.Generic.List%601%5BOrchardCore.Commerce.Abstraction.ViewModels.Region%5D&ShoppingCartId=4hap81e272txkszm6jrryh52xj&GrossTotal=%240.00&Provinces=System.Collections.Generic.Dictionary%602%5BSystem.String%2CSystem.Collections.Generic.IDictionary%602%5BSystem.String%2CSystem.String%5D%5D&UserEmail=&IsInvalid=False&SingleCurrencyTotal=%243.00&NetTotal=%243.00&OrderPart=OrchardCore.Commerce.Abstractions.Models.OrderPart&PaymentProviderData=System.Collections.Generic.Dictionary%602%5BSystem.String%2CSystem.Object%5D

UserEmail=&IsInvalid=False&SingleCurrencyTotal=%243.00&NetTotal=%243.00 are ok,
but OrderPart=OrchardCore.Commerce.Abstractions.Models.OrderPart&PaymentProviderData=System.Collections.Generic.Dictionary%602%5BSystem.String%2CSystem.Object%5D just gave out the name of the another class , not the data.

Expected behavior

OrderPart=OrchardCore.Commerce.Abstractions.Models.OrderPart&PaymentProviderData=System.Collections.Generic.Dictionary%602%5BSystem.String%2CSystem.Object%5D
should show the data like
CheckoutViewModel.OrderPart.Email=[email protected]&....
