Verified on 20x: https://qa20-mysql.nightly.sakaiproject.org/, build: fc3c08ab

@Brian J. it was the wrong delimiters! I looked in the Help docs and it says {} instead of $$ for wrapping the text. The test plan here had []. Marking as verified, looks like it's all good!

@Molly Kelsey, I'm not able to reproduce your issue. I tested on nightly master MySQL, and nightly 21.x MySQL, I was able to complete the test plan successfully for both. Here are the steps I took:
go to site
add lessons tool, enable mathjax
go to lessons
add question (short answer)
for the "Question Text", I used the following formula:
$$\sigma = \sqrt{ \frac{1}{N} \sum_{i=1}^N (x_i -\mu)^2}$$"Save"
Verify the formula renders
Edit the question
Verify the formula in the "Question Text" field remains unchanged
"Update Item"
Verify again that the formula renders correctly
The specific formula you use shouldn't matter, but the delimiters used do. Also, make sure your browser isn't blocking anything. I believe the nightly servers are configured to use MathJax source code hosted by Cloudfare, rather than having the resources locally.

Hi @Brian J., I just tested on 21.x and 12.x but am still seeing a version of the issue. Is there another place I should test? I have MathJax enabled

Assigning to Molly for testing.
In Lessons short question, if you have an MathJax equation:
sin�≈� from: [ \sin\theta\approx\theta ]
When you try to edit the equation, the edit box shows:
sin�≈� \sin\theta\approx\theta
which is incorrect.
Further feedback: This means "that delimiters have to be re-entered manually. This can become quite time-consuming when entering longer expressions, and especially if multiple edits need to be made."
