vscode-jupyter: Jupyter extension breaks code folding in ordinary python files

Environment data

VS Code version: 1.72.0, 64bbfbf67ada9953918d72e1df2f4d8e537d340e, x64
Jupyter Extension version: v2022.9.1002671058 and later are broken, v2022.9.1002661205 and earlier are fine; I bisected to this having found that v2022.8.1002431955 worked but the upgrade to 2022.9.1002791758 broke things
Python Extension version: v2022.16.0
OS and version: Ubuntu 20.04.5 LTS
Python version: at least Python 3.7 and 3.9 from deadsnakes, other versions untested
Type of virtual environment used: virtualenv, via virtualenvwrapper
Jupyter server running: none

Expected behaviour

Code folding in ordinary Python files should work. Historically it has worked based on indent levels.

Actual behaviour

Code folding does not work. No folding regions are detected, though regions which were folded in the previous session remain usable. Keyboard shortcuts for collapsing to a given “level” of folding do not work (nothing happens).

Steps to reproduce:

$ workon <env name>
$ code .
open a python file (in my case I have files which auto-opened as they were open in a previous session)
try to fold code, either by hovering over the sidebar or via keyboard shortcut

Note that I have not opened a Jupyter notebook in this workspace, either in this session or otherwise.

ok, looks like that is the reason then, and the python extension ran into the same problem 4 years ago - https://github.com/Microsoft/vscode/issues/50991

To workaround, you can add either of these settings: "jupyter.pythonCellFolding": false or "editor.foldingStrategy": "indentation".

To have both cell folding and indentation folding, pylance needs to be used as the language server so that the python extension provides folding regions. We may just end up disabling cell folding by default to avoid this situation.

It seems that "jupyter.pythonCellFolding": false is deprecated?

Using "editor.foldingStrategy": "indentation", in settings.json resulted in

.py file
.ipynb file

Is is possible for VSCode to support double folding strategy to support both # %% and indent at the same time?

Supremely annoying - I’ve resorted to disabling Jupyter, folding sections of code I’m not working on, and then re-enabling Jupyter.
