WorkAround:

Use onClick instead, (does not work fire event handler when details is opened with keyboard !)
namespaceURI = DOMNamespaces.mathml;
      }
    }
    this._namespaceURI = namespaceURI;
    if (__DEV__) {
      var parentInfo;
      if (hostParent != null) {
        parentInfo = hostParent._ancestorInfo;
      } else if (hostContainerInfo._tag) {
        parentInfo = hostContainerInfo._ancestorInfo;
      }
      if (parentInfo) {
        
        
        validateDOMNesting(this._tag, null, this, parentInfo);
      }
      this._ancestorInfo =
        validateDOMNesting.updatedAncestorInfo(parentInfo, this._tag, this);
    }
    var mountImage;
    var type = this._currentElement.type;
    if (transaction.useCreateElement) {
      var ownerDocument = hostContainerInfo._ownerDocument;
      var el;
      if (namespaceURI === DOMNamespaces.html) {
        if (this._tag === 'script') {
          
          
          var div = ownerDocument.createElement('div');
          div.innerHTML = `<${type}></${type}>`;
