### System information

### Issue description

![image](https://user-images.githubusercontent.com/2223172/231459722-294d88f9-dae3-4a3f-8e7f-e5340ca0dd25.png)
Both paths point to the same node, but the second one appears as if the node wasn't found. I assume this is because the NodePaths in array don't have the scene's node as "parent", so the path can't be resolved properly.

### Steps to reproduce

1.
```GDScript
@export var np1: NodePath
@export var np2: Array[NodePath]
```
2. Assign the same node
3. Compare the results

### Minimal reproduction project
