Dependency optimizer causes duplication of a linked monorepo package

[maxpatiiuk]

Describe the bug

In a monorepo project where both a package defined in the monorepo (consumer) and an external package (external-consumer) are consuming a shared package (common-package) that is defined in the monorepo, that shared package ends up being included twice in the dev server - once via pre-bundling, and once normally.

Reproduction

https://github.com/maxpatiiuk/vite-double-bundle

Steps to reproduce

1. npm install
2. cd packages/consumer
3. npx vite
4. Open browser console and see common-library logged twice.

• Follow our Code of Conduct
• Read the Contributing Guidelines.
• Read the docs.
• Check that there isn't already an issue that reports the same bug to avoid creating a duplicate.
• Make sure this is a Vite issue and not a framework-specific issue. For example, if it's a Vue SFC related bug, it should likely be reported to vuejs/core instead.
• Check that this is a concrete bug. For Q&A open a GitHub Discussion or join our Discord Chat Server.
• The provided reproduction is a minimal reproducible example of the bug.
