This is fine. Another way you could do this would be to run the script in a
script tag right after the contentEditable element. Then you wouldn't need to do
it on the load event, which means you could use the dump-as-markup auto dumping
and wouldn't need any of the Markup calls. Just including the dump-as-markup
script would be enough.

+  Markup.notifyDone();
