No grades page enhancements work

[ajs256]

Describe the bug

When I open the grades page, none of S+'s enhancements appear, but my theme and the (+) settings button show.

Steps to reproduce

1. Open the grade report or a course's grades page
2. Observe that none of S+'s enhancements appear

Expected behavior

To be able to see S+'s enhancements, including the percentage without expanding the course and the what-if mode checkbox.

Additional context

It appears that the grades script is loading in before jQuery, because I see these errors in the console:

Uncaught ReferenceError: $ is not defined
    at grades.js:25:1
Uncaught ReferenceError: modals is not defined
    at course.js:27:5
    at course.js:79:3

Platform

I'm using Arc 0.91.1, which is based on Chromium 112.0.5615.49. My Schoology domain is a custom subdomain of .schoology.com, and S+ is version 7.8.1.

Yeah unfortunately this is a known bug that I've spent a fair bit of time trying to understand, but I've made no progress. It seems to be a random thing that happens, and most of the time it's fixed by disabling and re-enabling the extension.

Unfortunately I don't have much helpful info beyond that right now.
