Newtonsoft.Json can serialize this successfully while System.Text.Json doesn't do it:

```cs
var la = new List<A> { new B() { I = 1, J = 2 } };
Console.WriteLine(Newtonsoft.Json.JsonConvert.SerializeObject(la));
Console.WriteLine(System.Text.Json.JsonSerializer.Serialize(la));

class A
{
    public int I { get; set; }
