Test plan:
* all the icons should look the same as they did before
* make sure that icons that should flip for RTL (like the icons on
The course/user search pagination arrows, the icon to open the
Submission details tray in new gradebook, the “>” icons to expand
a submenu for the menus in new gradebook, etc)
