Enable Always On Scrollbars on MacOS

Load https://jsfiddle.net/z2da3hec/17/

You will see that it renders almost entirely blue except for the scroll corner which renders plain white.

I would expect it to be colour matched to the scrollbar track colour.

It's worth noting this only appears to be an issue with overflow: scroll. When actual scrollbars render the scroll corner correctly matches the track colour. (Not fully dynamically but I will raise a separate issue for that)
