Poetry include bug?

Retrieving Poetry metadata

# Welcome to Poetry!

This will download and install the latest version of Poetry,
a dependency and package manager for Python.

It will add the `poetry` command to Poetry's bin directory, located at:

/root/.local/bin

You can uninstall at any time by executing this script with the --uninstall option,
and these changes will be reverted.

Installing Poetry (1.8.3): Done

Poetry (1.8.3) is installed now. Great!

To get started you need Poetry's bin directory (/root/.local/bin) in your `PATH`
environment variable.

Add `export PATH="/root/.local/bin:$PATH"` to your shell configuration file.

Alternatively, you can call Poetry explicitly with `/root/.local/bin/poetry`.

You can test that everything is set up by executing:

`poetry --version`

root@125be24bdd5c:/# export PATH="/root/.local/bin:$PATH"
root@125be24bdd5c:/# mkdir /root/poetryinclude
root@125be24bdd5c:/# cd /root/poetryinclude

WARNING: Running pip as the 'root' user can result in broken permissions and conflicting behaviour with the system package manager. It is recommended to use a virtual environment instead: https://pip.pypa.io/warnings/venv

[notice] A new release of pip is available: 24.0 -> 24.2
[notice] To update, run: pip install --upgrade pip
root@125be24bdd5c:~/poetryinclude# ls /usr/local/lib/python3.11/site-packages/CHANGELOG.md 
/usr/local/lib/python3.11/site-packages/CHANGELOG.md

Note that wheel contains CHANGELOG.md, and installing from the sdist puts CHANGELOG.md in site-packages. This does NOT happen if setting format=sdist, even though it is supposedly the default.
