I observed my students encountering the following issue in educational worlds:
If they open the code builder before any tutorial, the code editor shows “Coding is not required to complete your current activity.”
After a tutorial is opened, the code editor correctly displays the tutorial content.
However, when a student presses Backspace without selecting any instructions or blocks, the code editor reverts to the “Coding is not required to complete your current activity” screen, which prevents them from continuing the tutorial.
This suggests that pressing Backspace when no block is selected may be triggering the default “go back in history” behavior.
