  We wrap the <span> elements under test with <div> elements so the invalid
  value default (inherit) can be distinguished from true through the IDL
  attribute. The inherit state would otherwise yield true because inheritance
  would go all the way to :root, whose translation mode is translate-enabled
  because it’s also in the inherit state.
