1. Go to any lesson in the curriculum.
2. Enter the code editor, set focus to it.
3. Press alt+f1 to show accessibility help for the editor, and choose to enable the screen reader mode
4. complete the lesson, advance to the next, and repeat steps two and three

Expected behavior A clear and concise description of what you expected to happen. The screen reader mode should have stayed enabled across lessons. Screenshots If applicable, add screenshots to help explain your problem.
