Title: Modify CM margin (to rever later)

Fixes #3397, should also be reverted when closed by #3391
Cf #3358 also.

I can't test if this prevent the scrollbar from appearing, as I've never had the issue.

But for what I have seen, this have the Codemirror cell to always have a blank line at the end on FF, and the correct size on Chrome.
