How to copy displayed ellipsis when buffer content is folded?

Question

I have JSON files in which I am folding away some subnodes with the hideshow mode.

This works reasonably well. Now I want to create a new file or buffer with the folded content.

For example, my folded JSON buffer looks like:

{
  "type": "Helper",
  "name": "Walter",
  "skills": {...}
}

Then I want to copy exactly this text (with the three dots).

However, when I copy the buffer to the clipboard and paste it in another buffer, I get in the new buffer the expanded version:

{
  "type": "Helper",
  "name": "Walter",
  "skills": {
     "type": "list",
     "list": [ "latin", "maths" ]
  }
}

How can I tell Emacs to copy the text it displays, not the text which is in the underlying buffer?

PS: I tried origami.el as well - same problem.
