Bug

**What is the current behavior?**

React Native for Web was broken by 16.5 as describe [here](https://github.com/necolas/react-native-web/issues/1096) due to this change https://github.com/facebook/react/pull/13539

**What is the expected behavior?**

Release a version of React that exports the EventPluginHub.

**Which versions of React, and which browser / OS are affected by this issue? Did this work in previous versions of React?**

Worked in 16.4
