Describe the bug
I wanted to find all the 3rd party dependencies for some of my code so I ran:

./pants dependencies --dependencies-transitive --dependencies-type=3rdparty device/coordinator/

It output:

fastapi[all]
hypercorn
pydantic
requests
types-requests

but some of those dependencies also have dependencies which were not output. For example hypercorn depends on h2, h11, priority, etc. You can see the full list here: https://github.com/pgjones/hypercorn/blob/master/setup.py

Pants version
2.6.0

OS
Linux (not tested on Mac). Debian Bullseye to be specific.
