Vertical Divider Thickness / Environment Column Overflow Y

While looking at the component resizing PR, I noticed the space between the editor column and output is separated by a thick light gray area. I believe this is attributed to the overflow-y: scroll on the environment__column-contents rule. Taking it away seems to make the layout feel a bit cleaner and doesn't seem to make much of a difference in the scrolling experience as far as I can tell. Is there a reason for this rules existence that I am missing?

    position: absolute;
    top: 0;
    bottom: 0;
    left: 0;
    right: 0;
    overflow-x: hidden;
    **overflow-y: scroll;**
}```

Inizia individuando la regola .environment__column-contents e verifica in che modo il suo comportamento overflow-y: scroll influisce sul layout dell’editor e dell’output. Confronta il layout e l’esperienza di scorrimento dopo aver rimosso questa dichiarazione e conferma se il divisore spesso e l’overflow della colonna vengono risolti senza regressioni nello scorrimento.
