Right now the visual editor's iframe is set to width: 100% but for really narrow tutorial panes that can't be extended, that's still not great. Better would be for a horizontal scrollbar at the bottom of the iframe that allows the user to scroll to the right.
It's also possible that really long algorithms could go beyond the ~500px of vertical space we've allocated for that iframe, so allowing it to scroll vertically might help too.
