ubisoft.com incorrect blocking about popupblocker

It should be fixed by e43b496. This is caused by a react instance used in account management dropdown menu. It was previously undetected, and I added another selector check for react. Usage of such custom data-* attributes are being reduced in react (https://reactjs.org/blog/2016/04/07/react-v15.html#document.createelement-is-in-and-data-reactid-is-out) but they will still be present. If we encounter a case where this is not enough, we may need to go to a full-fledged approach as in react-devtools.
