The working directory of notebook sessions should always be the notebook's parent directory

Positron Version:

Positron Version: 2024.04.0 (Universal) build 29

Steps to reproduce the issue:

1. Open a Python notebook in a workspace with (or without) a folder opened.
2. Run !pwd to check the working directory.
3. The working directory will be the workspace directory, or the user's home directory if there are no workspace folders opened.

What did you expect to happen?

The working directory should be the notebook's parent directory.

Users write notebooks assuming that this is true e.g. when determining the paths to their datasets as in https://github.com/posit-dev/positron-beta/discussions/57 where this was originally posted.

This is the case in both Jupyter Lab and VSCode regardless of where you start Jupyter Lab or whether any workspace folders are opened.

Were there any error messages in the output or Developer Tools console?

No.

In Positron 2024.04.0 (Universal) build 1576, the working directory for a notebook session is right where the .ipynb is (even when different from the workspace directory):
