Describe the issue

Set up a poetry with 'jupyter', nix develop, try running jupyter notebook.
(After application of #1488).

Expected: Notebook in browser.
Actually: incomplete page load,
Console message:

Additional context

NixOS/nixpkgs#255923
and NixOS/nixpkgs#268078

But attempting that fix, by calling JUPYTER_PATH=<nix-store-path-where-the-files-actually_are> jupyter notebook does not change the path it's using, it still complains about the same path below the python3 nix store path.
