Remove unused vertical scrollbar gutter

[jonatanklosko]

[data-code] has overflow-y: clip, and overflow-x: scroll, so the effective overflow-y is actually hidden. Consequently, the vertical scrollbar can never appear, but scrollbar-gutter: stable can cause an empty gutter space to be reserved for the vertical scrollbar anyway. It does not always show up, but in our app it does show up in some cases and removing scrollbar-gutter: stable fixes that.

Given that scrollbar-gutter: stable only impacts the inline axis, here the vertical scrollbar, and said scrollbar should never appear, it seems like reserving a gutter is never desirable. I may be missing the original intent of the rule being added though.

It’s very much intentional because it keeps bottom padding consistent around hunk separators.

also it would break calculations in the virtualizers

My understanding is that scrollbar-gutter: stable does not impact horizontal scrollbars though, per the spec:

This property affects the presence of scrollbar gutters placed at the inline start edge or inline end edge of the box.

Does it actually change the spacing?
