Describe the bug
Cannot add more answer options for multiple choice questions. By default it provides 2 options and the first time I did this I was able to click a button and add a third, but then the button disappeared. And now the button never shows up so I can only have 2 answer options. I see there is json but I don't know the code to enter for the options. I also tried savign it to see if I could go back and edit and there is still not a button to add another option.

A Screenshot is worth a thousand words
Here is a screenshot from when I first encoutered this. Now I only have 2 options.

If you do not take the time to fill in this template we will treat this as very low priority.

Reproduce the issue at the instructor assignment builder URL and inspect the multiple-choice editor when adding answer options. Review the related frontend entry point and the reported browser console errors, especially the 404 and MathJax messages. Done means the add-option control remains available so a question can have more than two answer options after editing and saving.
