Preserve IFRAME content on drag

On my current project I am implementing the jHtmlArea WYSIWYG plugin on some TEXTAREA’s that are in rows that are draggable and sortable. The only problem is that once you begin dragging them they lose all the data that was in the IFRAME that the plugin masks over the associated TEXTAREA. jQuery’s .clone feature is being used but on its own it doesn’t carry all the data over with it and even setting it to .clone(true) or .clone(true, true) does not preserve the data on drag. Example:

Is there any way to preserve the content?
