WorkAround:

Use onClick instead, (does not work fire event handler when details is opened with keyboard !)
type : string,
    props : Object,
    rootContainerElement : Element,
    parentNamespace : string
  ) : Element {
    
    
    var ownerDocument = rootContainerElement.ownerDocument;
    var domElement : Element;
    var namespaceURI = parentNamespace;
    if (namespaceURI === HTML_NAMESPACE) {
      namespaceURI = getIntrinsicNamespace(type);
    }
    if (namespaceURI === HTML_NAMESPACE) {
      if (__DEV__) {
        warning(
          type === type.toLowerCase() ||
          isCustomComponent(type, props),
          '<%s /> is using uppercase HTML. Always use lowercase HTML tags ' +
          'in React.',
          type
        );
      }
      if (type === 'script') {
        
        
        var div = ownerDocument.createElement('div');
        div.innerHTML = '<script><' + '/script>';  
        
        var firstChild = ((div.firstChild : any) : HTMLScriptElement);
