Regression from #72277 (most likely, I didn't test)

### Steps to reproduce

1. Add some Node to your scene
2. Add a TileMap as a child
3. Select TileMap
4. Fold its parent in the scene tree
5. Restart the editor
6. The TileMap selection is restored and so is the folded node, resulting in a weird paradox
