[csswg-drafts] Setting the primary scrolling direction for an scrollable element (#10060)

Zhang-Junzhi has just created a new issue for https://github.com/w3c/csswg-drafts:

== Setting the primary scrolling direction for an scrollable element ==
Currently, almost all UAs assume the vertical direction is the first-class scrolling direction, so that UAs make vertical scroll as the _pure_ wheel event's default action, while making horizontal scroll as the wheel event's default action with an additional key(typically Shift Key).

That's a reasonable assumption for a page in horizontal writing page. A page in vertical writing mode, however, is another story, which is much more likely to overflow horizontally.

If we can set an element's primary scrolling direction, then the UAs know that it can make horizontal scroll as the _pure_ wheel event's default action.
