I don't know if this is intentional or not, but when I use the put the code editor into Fullscreen, only the first 15-20 lines appear and the rest of the page is black. When I scroll down I can see them, but it's as if the bottom half of the editor has a black curtain over the rest of the code.
I can reproduce, this happens if you navigate to a later page in the course and then go full screen, but not if you're on an early page where the editor hasn't been unlocked yet.
