We return the element style, and I think we should, if only, return a style inheriting from it, instead.

Simple testcase showing incorrect behavior:

  <div style="position: absolute"></div>
  <script>
    alert(getComputedStyle(document.querySelector("div"), "::before").position);
  </script>

alerts "absolute", which is wrong; should be "static".
