I found a minor bug in "this is just a test" reviews.
I was reviewing a late answer on StackOveflow, and a test review appeared. After reading the question to see if the answer had anything to do with it, I clicked on show comments
on the question. The Congrats, you passed
message appeared immediately and allowed me to continue to the next review, with the message being something similar to "Thanks for deciding to leave the user feedback".
