Great work Xidorn!!! Also as of *today* the W3C has published the first public working draft of CSS Scrollbars Module Level 1 which defines these properties: https://www.w3.org/TR/css-scrollbars-1/ > Other UAs don't currently have plan to ship it, They don't have explicit plans, however at least two have strongly indicated they would like to in past CSSWG f2f meetings. I think we can affect that by shipping.

The features have definitely benefited from public iteration.
