I don't know how one could fix that. I fear a scrollbar is not feasible for the import version.

Nvm, I think I fixed it, lol.

Confirmed, it works! 👍

Enter seems to be blocked. But using Shift + Enter I can still add blank lines.

That's exactly how all code boxes work in Arma, eg. editor object init fields.
