You can workaround with this for now:

10:54:12 AM: hint: If you want peer dependencies to be automatically installed, add "auto-install-peers=true" to an .npmrc file at the root of your project.
10:54:12 AM: hint: If you don't want pnpm to fail on peer dependency issues, add "strict-peer-dependencies=false" to an .npmrc file at the root of your project.

I noticed we don't actually have to use the @mdx-js/rollup dep, so refactoring that away should fix it.
