Copy of paragraphs in translation incomplete

When creating a translation of a node containing a Layout Paragraph field, the existing paragraphs are copied. In my case it seemed to be buggy. Only the top level paragraphs - only the layout paragraphs and its fields - are copied. The nested paragraphs are not copied.

We decided to remove all paragraph content on translation, as our client prefers to build translated pages from scratch. Instead of deleting content, they now can build starting with an empty paragraph field. I created a patch to remove all paragraph content.

Reported this because maybe someone else could benefit.
