[🐛 Bug]: [py] Installing package from a local source distribution in editable mode doesn't work

[cgoldberg]

Description

Steps to reproduce:

• Download a published source distribution package from PyPI (i.e. selenium-4.38.0.tar.gz from https://pypi.org/project/selenium/#files)
• Unarchive the tarball into a directory (i.e. ./selenium-4.38.0)
• Install it in editable mode (-e/--editable) from the local directory (i.e. pip install -e ./selenium-4.38.0)

Results:

The package succesfully builds (if you have a Rust toolchain installed) and installs, and you can import the main module... but no attributes or packages inside it are available.

If you install in non-editable mode (i.e. pip install ./selenium-4.38.0), everything works fine.

Environment:

• operating system: Linux (Debian 13) or Windows (11)
• python: 3.14
• pip: 25.3

Note: this is low priority, but I would like to figure out why it doesn't work

Reproducible Code

pip install --editable ./selenium
