WorkAround:

Use onClick instead, (does not work fire event handler when details is opened with keyboard !)
styleUpdates = {};
            }
            styleUpdates[styleName] = '';
          }
        }
      } else if (propKey === DANGEROUSLY_SET_INNER_HTML ||
                 propKey === CHILDREN) {
        
      } else if (propKey === SUPPRESS_CONTENT_EDITABLE_WARNING) {
        
      } else if (registrationNameModules.hasOwnProperty(propKey)) {
        
        
        
        if (!updatePayload) {
          updatePayload = [];
        }
      } else {
        
        
        (updatePayload = updatePayload || []).push(propKey, null);
      }
    }
    for (propKey in nextProps) {
      var nextProp = nextProps[propKey];
      var lastProp =

      if (!nextProps.hasOwnProperty(propKey) ||
          nextProp === lastProp ||
          nextProp == null && lastProp == null) {
