Outline shows duplicated "Jupyter" and "Python" entries

[joel-kelly]

The outline view in VSCode has recently started doing something mildly annoying where the outline entries are listed twice when I am editing a .py file, if I have a Jupyter notebook open at the same time.

I submitted this as a bug to the VSCode repo but they told me to bring it here.

Environment data

• VS Code version: 1.69.2
• Jupyter Extension version (available under the Extensions sidebar): v2022.6.1201981810
• Python Extension version (available under the Extensions sidebar): v2022.10.1
• OS (Windows | Mac | Linux distro) and version: Windows_NT x64 10.0.19043
• Python and/or Anaconda version: Python 3.9.7
• Type of virtual environment used (N/A | venv | virtualenv | conda | ...): conda
• Jupyter server running: Local

Expected behaviour

The outline view should only display one set of entries.

Actual behaviour

Two entries are displayed, see screenshot.

Steps to reproduce:

[NOTE: Self-contained, minimal reproducing code samples are extremely helpful and will expedite addressing your issue]

1. Open a .py file. Outline in the Explorer looks normal (displays classes, functions, etc).
   

2. Open a .ipynb notebook file. Outline displays Jupyter markdown cells, looks normal.

3. Switch back to the .py file. Outline now has "Jupyter" and "Python" headers for this .py file, which contains duplicated entries (same entries as in step 1: classes, functions, etc).

We don't actually provide the outline entries. Pylance does that as far as I know. Transferring there.

I see "no folder selected" does it happen if you use "Open Folder" ?
