One line uniquely

Hi,
I've seen that you have configured the permutation to have only one line element.
At line 126 line of code in  INGInious-problems-permutation/permutation-studio/src/Row.jsx
 you have written:
        this.valueTA.style.whiteSpace = 'nowrap';
Why this choice? Can you set the whiteSpace to 'normal' to allow multiline?
