[css-text-decor-3] text-underline-position: left | right should specify horizontal writing behavior

http://dev.w3.org/csswg/css-text-decor-3/#text-underline-position-property
says:
  # ‘left’
  #   In vertical writing modes, the underline is aligned as for
  #   ‘under’, except it is always aligned to the left edge of the
  #   text. If this causes the underline to be drawn on the "over"
  #   side of the text, then an overline also switches sides and is
  #   drawn on the "under" side.

  # ‘right’
  #   In vertical writing modes, the underline is aligned as for
  #   ‘under’, except it is always aligned to the right edge of the
  #   text. If this causes the underline to be drawn on the "over"
  #   side of the text, then an overline also switches sides and is
  #   drawn on the "under" side. 

This should specify what happens in horizontal writing modes.  My
guess is that the intent was to behave exactly as 'under', but the
specification should say so.
