WYSIWYG changes are not detected

When used in combination with the WYSIWYG Module and the TinyMCE editor changes to the body field are not detected when the editor is enabled. I think this is because WYSIWYG editors create an iFrame in designMode, which means it's editable, but changes to this frame are only written to the corresponding textarea on certain events, in this case I think the submission of the form triggers the writing... so maybe there's a way to trigger this behavior before we check for changes to the form.
