WorkAround:

Use onClick instead, (does not work fire event handler when details is opened with keyboard !)
type: 'update styles',
          payload: styleUpdates,
        });
      }
      CSSPropertyOperations.setValueForStyles(
        getNode(this),
        styleUpdates,
        this
      );
    }
