Quiz: Hide All Answers briefly shows if an answer is incorrect.

I have noticed recently that if you select the new quiz choice "Hide all answers", then if the learner selects an incorrect answer, the learner will briefly see a "X" in the radio button as the course animates to the next question. 

This looks like an unintended change. If you are trying to hide all answers, why would you let the user see which questions they got wrong?

I'm still not sure if I like this or not, but it does not seem like what I was expecting.
