Steps to reproduce the problem:
1. find an exam page with a question which requires you to reorder the answers
2. using Macbook track pad, zoom and you can see you can not change the order.
3. no problem when using the zoom function on the browser.

What is the expected behavior?
I expect the zoom function using the trackpad generates the same result as using the zoom function in the browser (i.e. using cmd+ +)

What went wrong?
The form did not work as intended.

Does it occur on multiple sites: No
