Steps to Reproduce:

1. Clone https://github.com/RDeluxe/rush-repro-955
2. Go to libraries/dtos/src/dtos/user.ts
   You will have a compiler error. Normally vscode should be able to auto import the missing decorators from class-validator

• Webstorm autocomplete works
• The repo use rushjs with pnpm

Rush strategy is to create a clean node_modules tree in /common/temp/node_modules.
After that rush create for each "packages" a new node_modules tree with symlink.
