Re: [csswg-drafts] [css-scrollbars-1] accessibility review [css-a11y] (#3315)

I proposed a tiny markup change here (hope I got the syntax right, not too hot with Bikeshed etc...was going by similar examples elsewhere in the doc) #4800

> UAs should enforce a minimum actual size of scrollbar width per WCAG 2.1 SC 2.5.5 Target Size

Possibly worth noting though that even today, UAs don't generally have large-enough default scrollbars (based on the 44x44 CSS px minimum dimensions mentioned in that WCAG SC). Might be worth softening the statement a bit, maybe "UAs should enforce a minimum actual size of scrollbar width, to ensure that it remains usable/operable by users - ideally, following suggested minimum sizes per WCAG 2.1 SC 2.5.5 Target Size" or similar? Just worry that this part may be summarily ignored otherwise (particularly as it's a AAA requirement in WCAG anyway).

An additional point that I didn't mention originally, as it's not strictly WCAG related: it may be worth also adding a note that warns/remiinds authors that if they do choose to go for `scrollbar-width: none`, they are essentially preventing mouse users from scrolling (unless those users have a scrollwheel, or the author provides an alternative programmatic scrolling mechanism).
