Don’t break words apart in the error box

Just noticed the error box is breaking words apart (e.g. "s/newline/tring").
This should not happen.

I also don’t think the error text should be monospace. Makes it a bit hard to read.

Another thing I noticed is that the app's CSS influences the overlay, so we should look into preventing that (e.g. bootstrap).
Would an iframe accomplish this?

Yea, iframe would do the trick (the reason I used iframe for syntax error overlay).
