Description

Adding a JsonElement via JsonArray.Add throws an exception with .NET 8. In .NET 7 it worked without throwing.

It is interesting that JsonArray.Add worked in .NET 7 but JsonValue.Create fails in both .NET 7/8 when passing in a JsonElement with ValueKind.Object/Array.

Regression in 1db4357 ?

Reproduction Steps

using System.Text.Json;
using System.Text.Json.Nodes;

var element = JsonDocument.Parse("""{"test":"hello world"}""");

var array = new JsonArray();
array.Add(element.RootElement); // .NET 8.0 throws here

Console.WriteLine(array.ToJsonString());

Expected behavior

Works without exception.

Actual behavior

Throws a System.InvalidOperationException: "The element cannot be an object or array."

   bei System.Text.Json.ThrowHelper.ThrowInvalidOperationException_NodeElementCannotBeObjectOrArray()
   bei System.Text.Json.Nodes.JsonValue.VerifyJsonElementIsNotArrayOrObject(JsonElement& element)
   bei System.Text.Json.Nodes.JsonValue.Create[T](T value, Nullable`1 options)
   bei System.Text.Json.Nodes.JsonArray.Add[T](T value)

Regression?

Yes, it works with .NET 7.0

Known Workarounds

For this particular case the JsonDocument could be added instead of the RootElement.
A general workaround would be #70427 (comment)
