layout: Fix conflict resolution for collapsed borders differing in color
https://www.w3.org/TR/CSS21/tables.html#border-conflict-resolution
> If border styles differ only in color, then a style set on a cell wins
> over one on a row, which wins over a row group, column, column group
> and, lastly, table.
