Comment:

 Even if it's not a complete patch, i'm asking for a review to confirm i'm
 going correct way in this.

 Whats right now is cooperation between wysiwyg and source modes inside
 undoManager, achieved by snapshot normalization (on demand, cached). Each
 mode keep their own snapshot. If one mode wants compare it's content with
 previous snapshot from other mode, it normalizes it. All undoManager code
 is reused inside sourcearea.

 Whats missing is selection support in source view. Question related to
 this - should bookmarks also be stored on per-mode basis ? Then bookmarks
 normalization method is needed.
