WorkAround:

Use onClick instead, (does not work fire event handler when details is opened with keyboard !)
case 'textarea':
        lastProps = ReactDOMFiberTextarea.getHostProps(domElement, lastRawProps);
        nextProps = ReactDOMFiberTextarea.getHostProps(domElement, nextRawProps);
        updatePayload = [];
        break;
      default:
        lastProps = lastRawProps;
        nextProps = nextRawProps;
        if (typeof lastProps.onClick !== 'function' &&
            typeof nextProps.onClick === 'function') {
          
          trapClickOnNonInteractiveElement(((domElement : any) : HTMLElement));
        }
        break;
    }
    assertValidProps(tag, nextProps);
    var propKey;
    var styleName;
    var styleUpdates = null;
    for (propKey in lastProps) {
      if (nextProps.hasOwnProperty(propKey) ||
         !lastProps.hasOwnProperty(propKey) ||
         lastProps[propKey] == null) {
        continue;
      }
      if (propKey === STYLE) {
        var lastStyle = lastProps[propKey];
        for (styleName in lastStyle) {
          if (lastStyle.hasOwnProperty(styleName)) {
            if (!styleUpdates) {
