Inheritance with RegisterAssembly depends on class order

[ypPascal]

When using Assembly registration, the order in which class are handle has an effect in the result.
If you take the exemple that follow, AFoo declaration is handled before Foo, so the serializer will register without discriminator convention.
Then when Foo is handled, it won't override AFoo.
As a result you get an error when trying to deserialize.
If I simply move AFoo declaration after Foo declaration, then it work properly.

using System.Text.Json;
using Dahomey.Json;
using Dahomey.Json.Attributes;

var json = """
            {
"MyProp": {
    "$type": "Foo",
    "Id": 1
}
}
""";

var jsonSerializerOptions = new JsonSerializerOptions();
jsonSerializerOptions.SetupExtensions();
var registry = jsonSerializerOptions.GetDiscriminatorConventionRegistry();

registry.RegisterAssembly(typeof(Encapsulator).Assembly);

var item = JsonSerializer.Deserialize<Encapsulator>(json, jsonSerializerOptions);

Console.WriteLine(item);

public class Encapsulator
{
    public AFoo MyProp { get; set; }
}

public abstract class AFoo
{
    public int Id { get; set; }
}

[JsonDiscriminator("Foo")]
public class Foo : AFoo
{
