I'll leave it to you to look into whether the Javascript HTML editor (eg ckEdit) supports hidden things which can't be accidentally deleted.
Also, to figure out the user experience, for example, when a user copies or moves a range which includes some invisible thing, and then scratches their head when something unexpected appears in Word!
Maybe you could have a show/hide toggle.
