Schoology updated icons revert to old versions

[RobotChickens]

Describe the bug

Our domain got access to a new UI update for Schoology. This update includes new icons for folders, to-do, and others. However, these icons only show for a second before being reverted to the old ones.

Steps to reproduce

All I do is open up Schoology without Schoology+ installed. Clearing my cookies and cache doesn't do anything.

Expected behavior

I expect the updated Icons to stay, but they keep changing back. I also thought this extension would fix it, but it didn't.
