       * The idea is that "color" inherits by default while "border-color" does

       * not.  So if the former is red and the latter is green on a parent, and

       * the child's border-color is set to "inherit", it'll be green only if

       * the child is inheriting from the parent.  If not, it'll either be

       * whatever the border-color is on what it's inheriting from, which will

       * be red if what it's inheriting from has the default (currentColor)

       * border-color).
