  Issue 3066: [css-writing-modes] Does vertical writing mode of an HTML body
  element cause an orthogonal flow?

  <meta name="assert" content="This test checks that when the root element has a &lt;body&gt; child element, then the principal writing mode is instead taken from the values of writing-mode and direction on the first such child element instead of taken from the root element. We also check that the computed value is unaffected by inheriting it into a pseudo element.">
