Expected behaviour

Calling getSelectedNotebookController() returns the controller.

Actual behaviour

It returns undefined.

Steps to reproduce:

1. Open a notebook with a local kernel
2. Start a kernel outside of VS Code (python -m notebook)
3. Run the command to connect to a remote kernel
4. Paste your server link
5. Reload VS Code as usual
6. notebook affinity is not updated, and if we need the controller it returns undefined
7. Reload VS Code again
8. Now it works
