WorkAround:

Use onClick instead, (does not work fire event handler when details is opened with keyboard !)
var dependency = dependencies[i];
      if (!(
            isListening.hasOwnProperty(dependency) &&
            isListening[dependency]
          )) {
        return false;
      }
    }
    return true;
  },
  trapBubbledEvent: function(topLevelType, handlerBaseName, handle) {
    return ReactBrowserEventEmitter.ReactEventListener.trapBubbledEvent(
      topLevelType,
      handlerBaseName,
      handle
    );
  },
  trapCapturedEvent: function(topLevelType, handlerBaseName, handle) {

      topLevelType,
      handlerBaseName,
      handle
