Is this a feature or a bug?

Please describe the actual behavior.

For some unknown reason I can't rush add -p @types/react anymore without installing a react version with a matching version.
Going to common-versions.json
and adding

"preferredVersions": {
    "@types/react": "16.9.0"
  },

will crash rush update with ... can't find ... /react/16.9.0 ...

whereas

"preferredVersions": {
"react": "16.9.0",
"@types/react": "16.9.0"
},

works.
There seems to some problem with the `@types` prefix.

Which package manager and package manager version are you using, and are you using the public npmjs.org registry, or a custom registry? Which version of Rush are you using?

Can you share a simple repro repo? I just tried this and it worked fine for me.

"rushVersion": "5.23.0",
"pnpmVersion": "4.12.5"

Sadly can't share the repo due to IP.
Maybe it is related to having a submodule with other react dependency versions which need to be declared in common-versions and thus no react appearing inside the generated package.json inside common/temp?
