merge_pr_28282: Propagate scrollbar-gutter to the viewport
@felipeerias felipeerias tagged this 13 Apr 04:22 
This CL implements the propagation of scrollbar-gutter from the
root element to the viewport.

Relevant CSSWG discussion:
  https://github.com/w3c/csswg-drafts/issues/6079

LayoutBox will not try to apply scrollbar gutters to the element
which propagated its overflow properties to the viewport
("viewport-defining element") to avoid duplicating the ones
that may be created by the viewport itself.

Note: following the current CSSOM View spec, clientWidth and
clientHeight in the viewport-defining element will return the
corresponding viewport dimension excluding the size of any
rendered scrollbars, but not excluding empty scrollbar gutters:
