pipx: [Windows] Unable to inject jaraco.clipboard

Describe the bug Today I’m upgrading my Python 3.8 envs with Python 3.9. reinstall-all failed (found executables missing), so I uninstalled manually and attempted to reinstall. After pipx install 'xonsh[ptk]', I attempted to inject two deps:

PS C:\WINDOWS\system32> pipx inject xonsh jaraco.clipboard
Internal error with venv metadata inspection.
Unable to install jaraco-clipboard.
Check the name or spec for errors, and verify that it can be installed with pip.
←[?25h
PS C:\WINDOWS\system32> pipx inject xonsh keyring
  injected package keyring into venv xonsh
done!

With --verbose:

PS C:\WINDOWS\system32> pipx inject --verbose xonsh jaraco.clipboard

Expected behavior The package should have installed correctly.

It looks like the problem is the manglingnormalization of the name. The package name is jaraco.clipboard not jaraco-clipboard:
