Fix .small-scrollbar style for chromium

.small-scrollbar is used on poster rating/status lists, but wasn't working because we also have the `scrollbar-width` property set, so now if the browser supports the webkit scrollbar styling, we will prefer that over scrollbar-width.

Don't know if this will break safari or whatever but hell if ima download that.

firefox scrollbar looks nice and this will let us keep using scrollbar-width: small wherever we want for that sweet smol bar action in ff
