It is not possible to drag and drop the answers of a "Drag and drop into text" question after clicking (and not dragging) two different answer options.

Steps:

1. Create a Quiz
2. Create a "Drag and drop into text" question with several answer options.
3. Preview the question.
4. Click on one answer option (without dragging it) and then on another one.
5. The two answers become highlighted and locked, it is not possible to drag or unlock these answers again (reloading the page helps).
6. Additionally, if two answers on the left are clicked, one of the remaining answers on the right disappears.

Also, the console displays a JS error: "Uncaught TypeError: targetPos is undefined."
