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
const run = function(config, hierarchyConfig, nativeEventConfig) {
  let max = NA;
  const searchForMax = function(nodeConfig) {
    for (const readableID in nodeConfig) {
      const order = nodeConfig[readableID].order;
      max = order > max ? order : max;
    }
  };
  for (const eventName in config) {
    const eventConfig = config[eventName];
    if (eventConfig.bubbled) {
      searchForMax(eventConfig.bubbled);
      searchForMax(eventConfig.captured);
    } else {
      searchForMax(eventConfig);
    }
  }
  
  const runData = registerTestHandlers(config, hierarchyConfig);
  
  const extractedEvents = ResponderEventPlugin.extractEvents(
    nativeEventConfig.topLevelType,
    nativeEventConfig.targetInst,
    nativeEventConfig.nativeEvent,
    nativeEventConfig.target,
  );
  
  
  
  EventPluginHub.runEventsInBatch(extractedEvents, true);
