Cannot accept terms&conditions after requesting security questions reset

I would like to rant about the fact that these questions are really annoying (and they really should not check capitals, and ...) but that is not the point of this issue.

I have requested a reset for the so manieth' time. Now I cannot click the checkbox on the bottom of the page and then proceed. (dutch page, if that matters). The page also seems very laggy. I checked the element inspector and noticed a very rapid update rate on the page. DOM was refreshed too rapidly and deselecting the checkbox.

This is on the https://account.mojang.com/me/secure page.
