Bug

What is the current behavior?
It is separating the following dependencies like so:

[email protected]:
  version "15.6.2"
  resolved "https://registry.yarnpkg.com/react/-/react-15.6.2.tgz#dba0434ab439cfe82f108f0f511663908179aa72"
  dependencies:
    create-react-class "^15.6.0"
    fbjs "^0.8.9"
    loose-envify "^1.1.0"
    object-assign "^4.1.0"
    prop-types "^15.5.10"

"react@^15 || ^16":
  version "16.0.0"
  resolved "https://registry.yarnpkg.com/react/-/react-16.0.0.tgz#ce7df8f1941b036f02b2cca9dbd0cb1f0e855e2d"
  dependencies:
    fbjs "^0.8.16"
    loose-envify "^1.1.0"
    object-assign "^4.1.1"
    prop-types "^15.6.0"

If the current behavior is a bug, please provide the steps to reproduce.

in package.json "react": "15.6.2" is in dependencies
"react-error-overlay": "2.0.2" is in devDependencies

What is the expected behavior?

@arcanis I remember us having an issue about improving deduplication/hoister. Do you think this falls into that?
