### Steps to reproduce

1. Open the minimal reproduction project or follow the instruction below:
    1. first reproduce the following tree (this is because of #76069) <img width="235" alt="Capture d’écran 2023-04-14 à 23 09 47" src="https://user-images.githubusercontent.com/66184050/232155382-da3f9e22-26fb-4e10-bdcb-07cb60c25ea1.png">
    2. add a script to the root and export a `NodePath` variable
    3. Set the exported variable to the `GrandChild` node
4. select all node except the root.
5. Batch rename `C` to `T` for example
6. Inspect the root node. You should have a broken `NodePath` and an error.
