`poetry export -o requirements.txt --without-hashes --with-credentials --all-extras` doesn't export all dependencies

Description

poetry export -o requirements.txt --without-hashes --with-credentials --all-extras doesn't export all dependencies.

Workarounds

I have to include all extra dependency groups with --with or use no groups at all.
Unfeasible in CI pipelines for example.

Poetry Runtime Logs

the command isn't failing, it's just not behaving as expected

Start by reproducing the documented poetry export -o requirements.txt --without-hashes --with-credentials --all-extras command in a project with dependency groups and extras. Compare its output with exports using --with or no group options; done means the --all-extras invocation includes all expected dependencies.
