latest pip (23.3) causes dependency oddity #2003
Description
When running pip-compile + pip 23.3 with a requirements.in containing pytest-cov, it shows a weird dependency list with coverage[toml] being installed because of a dependency on coverage. Note that actual package versions are completely fine, this seems to be purely cosmetic.
Things seem better with the previous pip 23.2.1.
Not sure what causes this -- it could pip, pip-tools, pytest-cov or coverage, but pip-tools has the best community vibes so I'm trying here first ;)
