How to add "rel" attribute in anchor tag in THYMELEAF application to avoid Phishing by Navigating Browser Tabs?

To avoid "Reverse Tabnabbing", I have added rel="noopener noreferrer" in all anchor tags in my Thymeleaf based application which is having target="_blank", but Thymeleaf is throwing exception as "Element type "a" must be followed by either attribute specifications, ">" or "/>" ".

Can anybody suggest how to add rel attribute so that Thymeleaf should except it in anchor tags ? Thanks in advance.
