JSON serializer ignores a base public property hidden by a new slot private one

[YohDeadfall]

The following code should serialize the MyString property of ClassWithPublicProperty, but it doesn't happen because GetProprties(BindingFlags.Instance | BindingFlags.Public) doesn't return base properties which are hidden by a new slot member.

var obj = new ClassWithNewSlotPrivateProperty();
string json = JsonSerializer.Serialize(obj);

public class ClassWithPublicProperty
{
    public string MyString { get; set; } = "DefaultValue";
}

public class ClassWithNewSlotPrivateProperty : ClassWithPublicProperty
{
    private new string MyString { get; set; } = "NewDefaultValue";
}

Expected: {"MyString":"DefaultValue"}
Actual: {}
