<p>For <a href="https://bugs.webkit.org/show_bug.cgi?id=84891">Bug 84891</a> -
mfenced add/remove child confusion.</p>

<p>This test passes if the mfenced is completely removed from the render tree,
so e.g. no parentheses or commas are showing after this paragraph.</p>

<math>
  <mfenced id="mfenced">
    <mi id="mi1">b</mi>
    <mi id="mi2">c</mi>
  </mfenced>
</math>
</body>

<script>
var mfenced = document.getElementById("mfenced");

document.getElementById("mi1").appendChild(document.createElement("div"));
mfenced.appendChild(document.createElement("span"));

var head = document.getElementsByTagName("head")[0];
var style = document.createElement("style");
style.appendChild(document.createTextNode("script{}"));
head.appendChild(style);

mfenced.parentNode.removeChild(mfenced);
