We missed this because Flow wasn't being run properly on Travis but now that it is, it's clear that #7716 introduced a bunch of new Flow failures. Most of these shouldn't be too bad and I like to say "you break it you buy it" so this one is for you @Aweary :)

There were a couple other pre-existing Flow issues that @vjeux is going to fix, so mostly this should just be the TestRenderer issues.

ReactBrowserEventEmitter.trapBubbledEvent(
              event,
              mediaEvents[event],
              node
            )
          );
        }
      }
      break;
    case 'source':
      inst._wrapperState.listeners = [
        ReactBrowserEventEmitter.trapBubbledEvent(
          'topError',
          'error',
          node
        ),
      ];
      break;
    case 'img':
      inst._wrapperState.listeners = [
        ReactBrowserEventEmitter.trapBubbledEvent(
          'topError',
          'error',
          node
        ),
        ReactBrowserEventEmitter.trapBubbledEvent(
          'topLoad',
          'load',
          node
        ),
