  Issue 229211: text-shadow is drawn at the invalid position in vertical writing mode
  on Chromium for Mac

  /*
  Value: [ <color>? && <length>{2,3} ]#
  color: color of text-shadow
  1st <length>
    Specifies the horizontal offset
    of the shadow. A positive value draws a shadow that is
    offset to the right of the box, a negative length to the
    left.
  2nd <length>
    Specifies the vertical offset
    of the shadow. A positive value offsets the shadow down,
    a negative one up.
