Hide window caret not visible for students

I’ve noticed the small caret (triangle) next to the instructions to hide\show the instructions window is not visible for students. It is when I am logged on but not for students. Screencast here:

Hi @GordonBrune,

It is hidden for me as well in both Chrome and Firefox. I’ll let support know. Thanks for finding this one!
