When the scrollbar is shown/hidden can be very jarring and cause the page to jump. The scrollbar-gutter and scrollbar-width CSS properties gives us some control but to my knowledge it doesn't allow us to make the transition from scrollbar to no scrollbar (and vice versa) a transition rather than a jump.
If this is the wrong place to post this, please let me know where I should post it and I'll do it :)
