Problem/Motivation

When an existing layout is duplicated, the elements contained within the layout are displayed in the reverse order in the duplicated version. For example, the below screenshot:
aa

Steps to reproduce

  1. install a vanilla drupal with layout_paragraphs version 3
  2. configure a section or container (a paragraph with layout_paragraphs enabled)
  3. add a simple text paragraph
  4. add a content type with a reference field to these paragraphs (multiple value)
  5. go to the node creation form/page and add a title, add a "section" paragraph
  6. I used the two column layout, but try others why not
  7. add multiple text paragraph instances in a fashion that makes the order clear
  8. save the node, then come back to edit (so far so good)
  9. now click on "duplicate" button in the layout icons and you will see the order reversed for the new duplicated paragraphs!
