Peter, I'd guess the decoder in your onChange is failing, causing the event
not to send a Msg. The decoder is going to get an event object, not a DOM
node, which is probably why decoding an "innerHTML" property is failing.
(Did your comment mean that your event handler does work for
non-contentEditable divs?)
