Automatic update from web-platform-tests Update scrollbar-gutter to new version of the spec Update the implementation of scrollbar-gutter to match the new spec: https://drafts.csswg.org/css-overflow-4/#scrollbar-gutter-property The syntax is is simplified to: auto | stable && mirror? The "stable" value also applies when overflow is "hidden". The "always" and "force" keywords have been removed. The "both" keyword has been renamed to "mirror". This CL updates all affected tests to match the new spec.
