Scrolleable div inside a -webkit-column-count

Placing an overflow scroll element inside some content with -webkit-column-count > 1 doesn't change column if it doesn't fit on the first one.

However, this can be avoided using some hardware acceleration on the scroll element.

See attached for a quick demo.

Safari 15.5+ now handles this case properly.
