pytest reproducer

When using the following together, pytest 7.4.4 fails to import from the correct module. The bug triggers in pytest’s collection phase.

Necessary for the bug to trigger:

• --import-mode=importlib
• --doctest-modules
• src/ layout
• no editable install

Run with e.g.

hatch run pytest
# or if you like typing
python -m virtualenv .venv; source .venv/bin/activate; pip install .; pytest
