Paragraph can't be added, deleted or moved in a translated node

Problem/Motivation

--- !!! I am not talking about asynchronus translation !!!---

If the paragraph field is set as not translatable and Hide non translatable fields on translation forms is not checked then we could expect to edit the paragraph in any language:
-deleting an item in french will lead to a deleted item in all languages
-moving an item in dutch will lead to a moved item in all languages
-idem for adding an item
-Editing is already working in all languages

This is the way the other fields are working, this is why I tag this issue as a bug

Steps to reproduce

1-Create a paragraph field
2-Set it as non translatable
3-Uncheck Hide non translatable fields on translation forms for the content type of the field
4-Create a node and translate it
5-Go to the translated node, you will not be able to add, delete or move a paragraph item
