command `pnpm why` returns nothing about pnpm

Issue #6995 might be partially related, but the pnpm list command works fine for me and only, like described, the pnpm why is broken.

@manniL and I tried to investigate it a little further and found out that it does not affect all packages.
In the following, I only point out random samples from the example repo I provided above, both directly installed dependencies from the package.json and sub-dependencies.

❌ Some not working ones:

$ pnpm why nuxt
$ pnpm why vue

✔️ Some working ones:

$ pnpm why socks
