  <meta name="assert" content="This test checks that 'background-image' applies to ::first-letter pseudo-element and that, in case of multiple background images, the first specified one must be on top (closest to the user).">

  <style>
  div
    {
      color: transparent;
      /* So that background shines through both "A" and "Z" glyphs */
      line-height: 1;
    }

  div::first-letter
    {
      background-color: red;
      background-image:
        url("data:image/svg+xml,<svg xmlns='http://www.w3.org/2000/svg' style='background: green'></svg>"),
        url("data:image/svg+xml,<svg xmlns='http://www.w3.org/2000/svg' style='background: red'></svg>");
      font-family: Ahem;
      font-size: 100px;
    }
  </style>

  <p>Test passes if there is a filled green square and <strong>no red</strong>.
