Can't add peer dependency if it is already a dev dependency

[thefat32]

When trying to add a peer dependency that is already a dev dependency got following warning and it is not added as peer

yarn init
yarn add react --dev
yarn add react --peer

warning "react" is already in "devDependencies". Please remove existing entry first before adding it to "peerDependencies".

package.json

{
  "name": "yarn-deps",
  "version": "1.0.0",
  "main": "index.js",
  "author": "thefat32",
  "license": "MIT",
  "devDependencies": {
    "react": "^18.2.0"
  }
}

However add the dependency first as peer and then as dev works correctly

yarn init
yarn add react --peer
yarn add react --dev

package.json

{
  "name": "yarn-deps",
  "version": "1.0.0",
  "main": "index.js",
  "author": "thefat32",
  "license": "MIT",
  "peerDependencies": {
    "react": "^18.2.0"
  },
  "devDependencies": {
    "react": "^18.2.0"
  }
}
