For reference, here's the code which ext-js uses to emulate insertAdjacentHTML:

    var N = R.ownerDocument.createRange();
    var S;
    switch (P) {
      case "beforebegin":
        N.setStartBefore(R);
        S = N.createContextualFragment(Q);
        R.parentNode.insertBefore(S, R);
        return R.previousSibling;
      case "afterbegin":
        if (R.firstChild)
          {
            N.setStartBefore(R.firstChild);
            S = N.createContextualFragment(Q);
            R.insertBefore(S, R.firstChild);
            return R.firstChild;
          }
        else
          {
            R.innerHTML = Q;
            return R.firstChild;
          }
      case "beforeend":
        if (R.lastChild)
          {
            N.setStartAfter(R.lastChild);
            S = N.createContextualFragment(Q);
            R.appendChild(S);
            return R.lastChild;
          }
        else
          {
            R.innerHTML = Q;
            return R.lastChild;
          }
      case "afterend":
        N.setStartAfter(R);
        S = N.createContextualFragment(Q);
        R.parentNode.insertBefore(S, R.nextSibling);
        return R.nextSibling;
    }
    throw "Illegal insertion point -> \"" + P + "\"";
