WorkAround:

Use onClick instead, (does not work fire event handler when details is opened with keyboard !)
continue;
      }
      if (propKey === STYLE) {
        if (__DEV__) {
          if (nextProp) {
            
            
            Object.freeze(nextProp);
          }
        }
        if (lastProp) {
          
          for (styleName in lastProp) {
            if (lastProp.hasOwnProperty(styleName) &&
                (!nextProp || !nextProp.hasOwnProperty(styleName))) {
              if (!styleUpdates) {
                styleUpdates = {};
