WorkAround:

Use onClick instead, (does not work fire event handler when details is opened with keyboard !)
'cancel',
              mountAt
            );
          }
          isListening.topCancel = true;
        } else if (dependency === 'topClose') {
          if (isEventSupported('close', true)) {
            ReactBrowserEventEmitter.ReactEventListener.trapCapturedEvent(
              'topClose',
              'close',
              mountAt
            );
          }
          isListening.topClose = true;
        } else if (topEventMapping.hasOwnProperty(dependency)) {
          ReactBrowserEventEmitter.ReactEventListener.trapBubbledEvent(
            dependency,
            topEventMapping[dependency],
            mountAt
          );
        }
        isListening[dependency] = true;
      }
    }

    var isListening = getListeningForDocument(mountAt);
    var dependencies =
