Updating Binding of InspectorElement doesn't get repainted in Editor

I'm trying to go through a list of scriptable objects by updating the object that the Inspector Element bound to. However, the inspector doesn't get updated or repainted in the editor after I invoke Inspector.Bind. Does it suppose to work this way? am I missing sth here?

Code (CSharp):

1. using UnityEditor;
2. using UnityEngine;
3. using UnityEngine.UIElements;
4. using UnityEditor.UIElements;
5. using VolatileBytes.eol.Entity;
6.  
7.  
8. public class CharacterCreatorWindow : EditorWindow
9. {
10.     private CharacterDatabase _characterDatabase;
11.     private AssetReference _assetReference;
12.     private CharacterEntity _current => _characterDatabase.entities[_currentIndex];
13.     private int _currentIndex = 0;
14.     private InspectorElement _entityInspector;
15.  
16.  
17.     [MenuItem("Window/UIElements/CharacterCreatorWindow")]
18.     public static void ShowExample()
19.     {
20.         CharacterCreatorWindow wnd = GetWindow<CharacterCreatorWindow>();
21.         wnd.titleContent = new GUIContent("CharacterCreatorWindow");
22.     }
23.  
24.     public void OnEnable()
25.     {
26.         _assetReference = AssetDatabase.LoadAssetAtPath<AssetReference>
27.             ("Assets/VolatileBytes/eol/Data/AssetReference.asset");
28.         _characterDatabase = _assetReference.CharacterDatabase;
29.         // Each editor window contains a root VisualElement object
30.         VisualElement root = rootVisualElement;
31.  
32.         // Import UXML
33.         var visualTree =
34.             AssetDatabase.LoadAssetAtPath<VisualTreeAsset>(
35.                 "Assets/VolatileBytes/eol/Editor/CharacterCreator/CharacterCreatorWindow.uxml");
36.         var styleSheet =
37.             AssetDatabase.LoadAssetAtPath<StyleSheet>(
38.                 "Assets/VolatileBytes/eol/Editor/CharacterCreator/CharacterCreatorWindow.uss");
39.         VisualElement view = visualTree.CloneTree();
40.         view.styleSheets.Add(styleSheet);
41.         var ve = view.Query<VisualElement>("character-entity-drawer").First();
42.         _entityInspector = new InspectorElement(_current);
43.         ve.Add(_entityInspector);
44.         RegisterEventHandlers(view);
45.         root.Add(view);
46.     }
47.  
48.     public void RegisterEventHandlers(VisualElement view)
49.     {
50.         var btnNext = view.Query<Button>("btn-next").First();
51.         var btnPrev = view.Query<Button>("btn-prev").First();
52.         btnNext.clicked += NextEntity;
53.         btnPrev.clicked += PrevEntity;
54.     }
55.  
56.     private void NextEntity()
57.     {
58.         if (++_currentIndex >= _characterDatabase.entities.Count)
59.         {
60.             _currentIndex = 0;
61.         }
62.  
63.         _entityInspector.Unbind();
64.         _entityInspector.Bind(new SerializedObject(_current));
65.         _entityInspector.MarkDirtyRepaint();
66.         Debug.Log("Bind data:" + _current.name);
67.     }
68.  
69.     private void PrevEntity()
70.     {
71.         if (--_currentIndex < 0)
72.         {
73.             _currentIndex = _characterDatabase.entities.Count - 1;
74.         }
75.  
76.         _entityInspector.Unbind();
77.         _entityInspector.Bind(new SerializedObject(_current));
78.         _entityInspector.MarkDirtyRepaint();
79.     }
80. }

 

Bug Reported (Case 1299036)

 

Link to final result in the IssueTracker https://issuetracker.unity3d.com/product/unity/issues/guid/1299036

I believe it's still reproducible with Unity 2021.2.0b2.3053 (built-in UI Toolkit) .
