Listen and Type: answer auto-completed?
I am using Safari on OS X 10.8.5 and noticed today that when I start typing in the box in the "listen and type" questions, the sentence is auto-completed while I type. Often the sentence is another one than the one that I am trying to type (or even in another language - i.e. French vs. Spanish), but they are always Duolingo sentences.
