PrefabUtility.UnpackPrefabInstance deslects other objects

So I have a problem. PrefabUtility.UnpackPrefabInstance seems to deselect current selection (and thus destroy active Editors, which in turn Disposes serializedObjects)

This is a problem.
Especially when you want to write a DragAndDrop handler for an Editor that might need to Unpack the dragged object during processing of the drag. Here's what's going on:

Code (CSharp):

1.  
2. void OnEnable() {
3.  
4.     list = serializedObject.FindProperty("list");
5. }
6.  
7. void OnDisable() {
8.  
9.     Debug.Log("Hi, I got disabled during drag and drop, isn't that fun!");
10. }
11.  
12. public override void OnInspectorGUI() {
13.  
14.     serializedObject.Update();
15.  
16.     HandleDragAndDrop();
17.  
18.     serializedObject.ApplyModifiedProperties();
19. }
20.  
21. void HandleDragAndDrop() {
22.  
23.     //drag and drop code ommited
24.  
25.     //process the drag and drop object "instance"
26.  
27.     if (PrefabUtility.IsAnyPrefabInstanceRoot(instance)) {
28.  
29.         //This method causes Unity to deselect the current selection. Causing the serializedObject on Editor to be disposed!
30.  
31.         PrefabUtility.UnpackPrefabInstance(instance, PrefabUnpackMode.OutermostRoot, InteractionMode.AutomatedAction);
32.     }
33.  
34.     //save instance as prefab
35.  
36.     bool success;
37.     GameObject prefab = PrefabUtility.SaveAsPrefabAssetAndConnect(instance, assetPath, InteractionMode.AutomatedAction, out success);
38.  
39.     //add instance to list *ERROR* - NullReferenceException: SerializedObject of SerializedProperty has been Disposed.
40.  
41.     list.GetArrayElementAtIndex(dragAndDropIndex).objectReferenceValue = instance;
42. }
43.  

Would be super great if it did not change Selection, or dispose current Editor after Unpacking.
