Double scroll bar visible while editing long instructions

[jwang1919]

Can see two scroll bars with long instructions. Open: https://popcode.org/?gist=a6f4b9bfd0b42b494346ff15abb43ab6 and edit the instructions. Reduce window size until the scroll bar shows up. You will notice the two scroll bars next to each other.

If you’re a Mac user, you should turn on always-visible scroll bars (a good idea for web developers anyway!)
