pnpm: pnpm does not include dependencies of dependents when filtering

pnpm version:

5.8.0

Code to reproduce the issue:

have three packages:

• @mono/a
• @mono/b
• @mono/c (depends on @mono/a)

Now (assuming you have jq installed), try running:

pnpm exec --filter ...@mono/b... -- cat package.json | jq '.name'

Expected behavior:

You’d expect to see:

@mono/a
@mono/b
@mono/c

Actual behavior:

But you actually see:

@mono/b
@mono/c

This means, for instance, if you’re doing a filtered install, and want to do a filtered build (TypeScript), you’ll likely end up in a situation where a dependent package can’t be built – because it wasn’t “installed” (specifically, @mono/a in that case wouldn’t have a node_modules folder).

• node -v prints: 12.18.4
