Peer Dependency Resolution Issue (webpack/jest/pnpm)

This repo demonstrates an issue with jest and webpack where module resolution does not respect the peerDependencies property. The test-package repo has a devDependency and peerDependency on jotai, but webpack and jest do not respect this and use the version of jotai installed under ./packages/test-package/node_modules/jotai.

Steps to reproduce (jest)

Run the test in test-app

cd packages/test-app
pnpm test

Steps to reproduce (webpack)

Run the local app in test-app

cd packages/test-app
pnpm start

What's wrong?

Expected: All Counter components have independent state

Actual: Two of the counters have shared state because there are two versions of jotai being loaded.
