  Issue 229211: text-shadow is drawn at the invalid position in vertical writing mode
  on Chromium for Mac
  https://bugs.chromium.org/p/chromium/issues/detail?id=229211#c8

  <meta content="This test checks that text-shadow offsets are purely physical and do not change with vertical writing mode.">

  div
    {
      color: yellow;
      font-family: Ahem;
      font-size: 100px;
      line-height: 1;
      margin: calc(1em + 8px) auto auto 1em;
      text-orientation: upright;
      writing-mode: vertical-rl;

      text-shadow: 0em -1em purple, 1em 0em blue, 0em 1em fuchsia, -1em 0em orange;
    }

  /*

  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.
