I’ve just had a quick go at this @Don, and based on the screenshot in the OP [1] the icons are red, so it means that the post has been deleted rather than at the ‘visible but (topic deleted by author) stage’.
Once it’s been deleted I can see, as admin, the un-delete options as normal:
Though if it’s still at the visible ‘(topic deleted by author)’ stage then it hasn’t been deleted yet and counts as a post edit, in which case you’d be right.
