WorkAround:

Use onClick instead, (does not work fire event handler when details is opened with keyboard !)
this._domID = 0;
    this._wrapperState = null;
    if (__DEV__) {
      setAndValidateContentChildDev.call(this, null);
    }
  },
  restoreControlledState: function() {
    switch (this._tag) {
      case 'input':
        ReactDOMInput.restoreControlledState(this);
        return;
      case 'textarea':
        ReactDOMTextarea.restoreControlledState(this);
        return;
      case 'select':
        ReactDOMSelect.restoreControlledState(this);
        return;
    }
  },
  getPublicInstance: function() {
    return getNode(this);
  },
};
Object.assign(
  ReactDOMComponent.prototype,
  ReactDOMComponent.Mixin,
  ReactMultiChild
);
module.exports = ReactDOMComponent;
