I just tested on my Android. Originally no problems but I realized as I hit buttons there, it would cause pop-ups. After toying with settings, it seems switching up the settings on the site to Block Scripts resolves the problem.
It’s actually fortunate as Block Scripts can often break these types of sites where content doesn’t open. But for this site, it doesn’t seem to be the case. Give it a try for yourself. I wouldn’t change the setting on global but go to the site, hit the Brave Lion/Shields icon, go to Advanced Controls, and turn on Block Scripts
