It appears this is not completely fixed; I am finding new examples such as this
one:

<BODY></BODY>
<SCRIPT>
  document.designMode = "on";
  document.execCommand("selectall");
  document.execCommand("InsertParagraph");
  document.execCommand("inserthorizontalrule");
  document.designMode = "";
  document.execCommand("Undo");
  document.designMode = "on";
  document.execCommand("Strikethrough");
</SCRIPT>

Causes:
