Multiple instances of a pkg

[aruniverse]

Hi,

I'm using yarn v3 in one of my monorepos. I'm running into an issue where only 1 person on my team is running into this react runtime error because there are multiple instances of react-dom in his install.

When we run yarn info -A react-dom I see there are 2 instances, but when looking through the yarn.lock file manually I only see 1 instance. We tried running yarn dedupe react-dom but that had no effect. Is there an issue with how peer deps are resolved? I know pnpm workpsaces has a very similar issue where multiple instances for peers get installed: https://pnpm.io/how-peers-are-resolved
