Fix: IE destroying nodes which have a Javascritp reference on using innerHTML

* It appears that if you have a reference to a DOM node, but that DOM
  node is overwritten by use of innerHTML, the reference is destroyed
  and you cannot use the referenced DOM node any more.
* This became apparent from using Editor's inline editing mode, where in
  IE the inline edit would work only once. No other browser has this
  issue but it is in IE7-DC1.
* The workaround is to remove the child nodes first. not ideal at all,
  but it does work.
* Searching the internet I didn't find much about this so I've opened an
  issue on the IE connect site:
