System.Text.Json: The polymorphism attributes do not appear to work with nested objects

[dcooperch]

Type of issue

Missing information

Description

The documentation does not mention anything about nested objects.

Consider the following code:

[JsonPolymorphic]
[JsonDerivedType(typeof(Derived1), typeDiscriminator: "Derived1")]
[JsonDerivedType(typeof(Derived2), typeDiscriminator: "Derived2")]

This only appears to work at the root level model.
