WorkAround:

Use onClick instead, (does not work fire event handler when details is opened with keyboard !)
return '\n' + ret;
    } else {
      return ret;
    }
  },
  _createInitialChildren: function(transaction, props, context, lazyTree) {
    
    var innerHTML = props.dangerouslySetInnerHTML;
    if (innerHTML != null) {
      const innerHTMLContent = innerHTML.__html;
      if (innerHTMLContent != null && innerHTMLContent !== '') {
        DOMLazyTree.queueHTML(lazyTree, innerHTMLContent);
      }
    } else {
      var contentToUse =
        CONTENT_TYPES[typeof props.children] ? props.children : null;
      var childrenToUse = contentToUse != null ? null : props.children;
      
      if (contentToUse != null) {
        
        
        
        
        if (contentToUse !== '') {
          if (__DEV__) {
            setAndValidateContentChildDev.call(this, contentToUse);
          }
          DOMLazyTree.queueText(lazyTree, contentToUse);
        }
