Hi Christian ,
The requested feature is almost the same as selecting the same content / tag when toggling back from HTML mode to Design mode. Both modes are different iframes which means different documents and it is not trivial to restore the cursor position when changing the iframes when switching between different view modes. In addition, the content is parsed by the editor's content filters to make it valid XHTML. This process modifies the content and it is not possible to programmatically restore the selection.
Have you seen by any chance another web based Rich Text Editor that supports this nice feature?
