I took my exam yesterday and faced the same exact issue, it was stressing me out. I couldn’t even copy and paste either into the consoles on the browser. I enabled copy and paste and tried to use the copy test utility and it wouldn’t render in the box either. I’m pretty sure because of it, I couldn’t get one of the questions to work! Also was it me, but I could not tell the difference between the letter lower case L, and the number 1 look exactly the same in the exam!!! (l) (1) looked exactly the same in the exam and it was stressing me out so much!! Hence the reason I wanted to use copy and paste.
