Card 49 has a link pasted into it, which is the correct answer. When I move from another card to it, it opens that link in another tab, which gives away the correct answer and is somewhat surprising

Huh! Very interesting, I can reproduce it.
Not obvious why this happens, I'll keep an eye on it & try to fix it when I get some time.
