Numerical hints in fill-in-the-blank-from-box are clickable but add number instead of word to input

In the fill-in-the-blank widget with a word box, if you type a number, it will add a label to each word in the word box so you can type 1-2-3 instead of clicking the first, second, and third words to answer the question. The hints, which appear as 1 in the top left of the word box, are clickable, but they add the 1 to the input instead of the word that 1 represents.
