pnpm version: 8.6.0

Code to reproduce the issue:

https://github.com/klingenm/dedupe-peer-dependents-repro

Expected behavior:

The peer:

/@apollo/client/3.7.1(graphql@15.8.0)(react@16.8.0) maps to /@apollo/client/3.7.1(graphql@15.8.0)(react-dom@16.8.0)(react@16.8.0)

and

/@apollo/client/3.7.1(graphql@15.8.0)(react@18.2.0) maps to /@apollo/client/3.7.1(graphql@15.8.0)(react-dom@18.2.0)(react@18.2.0)

Actual behavior:

Both:

• /@apollo/client/3.7.1(graphql@15.8.0)(react@16.8.0)
• /@apollo/client/3.7.1(graphql@15.8.0)(react@18.2.0)
  maps to

/@apollo/client/3.7.1(graphql@15.8.0)(react-dom@18.2.0)(react@18.2.0)
