| key | The key for the current VisualElement to be used with the persistence store on the EditorWindow. |
| obj | Object to overwrite. |
Overwrite object from the persistent data store.
This will overwrite all public and [SerializeField]-marked fields on the given object (meant to usually be the current VisualElement). It's better to use this method if the fields you want to persist on your VisualElement are mostly basic types and you don't want to create a class for them.
