Frontend editing may not apply value changes of nested paragraphs

I think this issue i not to do with frontend_editing Contrib module, i think its related to Paragraphs and Paragraph_edit contrib modules, because they are both have issue with render caching of Paragraph-referenced entities and nested Paragraphs.

If we just put this piece of code, in frontend_editing.module , this will also fix the problem.

  foreach (Element::children($build) as $key) {
    $cache_metadata = new CacheableMetadata();
    foreach (Element::children($build[$key]) as $child) {
      $cache_metadata = $cache_metadata->merge(CacheableMetadata::createFromRenderArray($build[$key][$child]));
    }
    $cache_metadata->applyTo($build[$key]);
  }

what do you think, should i prepare a patch for that?

@hanan alasari Yes, please.

The problem with nested paragraphs not reflecting the change that was done with frontend editing is due to wrong root_parent object that was passed to paragraph edit form, it should be not just the parent of current paragraph, but the root parent of the whole lineage of nested paragraphs, in the case of example, it is the node that has the paragraph reference field.

Please check the MR.

Tested and working.
