This but was very hard to reproduce. I suggest you try to reproduce it before you try to test the fix. You must be using Chrome for this. It is probably easier to reproduce if you are using a test server across a network, not a localhost install. Create a quiz and add many (10) drag-drop into text question. (Make one, duplicate several times with small edits.) Attempt the quiz, answering the questions, then submit. On the review page, ensure that all the drag items are displayed correctly positioned. (With the bug, sometimes they appeared in the wrong position vertically, but the right horizontal position - see screen grab.) Reload the review page several times, bother with F5, and also by clicking in the URL bar and pressing enter. After each reload, verify the drag items are correctly positioned. Check in the JavaScript console to verify there are no errors.
