Bug TrackPropertyValue not work in SerializeReference

I add some test code:

Code (CSharp):

1.  
2. using System;
3. using UnityEditor;
4. using UnityEditor.UIElements;
5. using UnityEngine;
6. using UnityEngine.UIElements;
7.  
8. public class TestBehaviour : MonoBehaviour
9. {
10.     public Weapon weapon1;
11.  
12.     [SerializeReference]
13.     public IWeapon weapon2 = new Weapon();
14. }
15.  
16. public interface IWeapon
17. {
18. }
19.  
20. [Serializable]
21. public sealed class Weapon : IWeapon
22. {
23.     public string name;
24.     public int damage;
25. }
26.  
27. [CustomPropertyDrawer(typeof(Weapon))]
28. public sealed class WeaponDrawer : PropertyDrawer
29. {
30.     /// <inheritdoc/>
31.     public override VisualElement CreatePropertyGUI(
32.         SerializedProperty property)
33.     {
34.         var root = new VisualElement { pickingMode = PickingMode.Ignore };
35.         root.Add(new TextField("Name") { bindingPath = "name" });
36.         root.Add(new IntegerField("Damage") { bindingPath = "damage" });
37.  
38.         root.TrackPropertyValue(property, _ =>
39.         {
40.             UnityEngine.Debug.Log("TrackPropertyValue");
41.         });
42.  
43.         return root;
44.     }
45. }
46.  

The 'TestBehaviour' has two weapon: weapon1 is normal SerializedField, and weapon2 is SerializeReference.
In the WeaponDrawer, I add a TrackPropertyValue to log information whenever any property changed.
When modify weapon1, the log will show in the console. But modify weapon2, nothing happen.

I am using the Unity 2022.2.0b8

 

I'm facing the same issue in 2022.2.1f1.

I am currently using TrackSerializedObjectValue as a workaround, but I would prefer if Unity fixed this bug for performance reasons.

 

same problem with 2022.2.2f1

 

Same on 2021.3.16f1, except instead of [SerializeReference] I'm editing a property with
[field: SerializeField].
