Content reset to source after a translation has been generated

Problem/Motivation

After cloning a piece of content (without modifying it, but having modified the source after cloning) and generating the translation of the clone, I notice that the content of the cloned page is updated with the content of the source that was previously modified.

Steps to reproduce

1. create content with a paragraph
2. duplicate this content
3. edit the source
4. generate a translation of the cloned version (manually or using tmgmt – it’s the same)

=> the original language of the clone is reset to the cloned content (and therefore includes the edit), whilst the translation remains correct

Proposed resolution

This appears to be linked to the paragraph entity, which in some way remains linked to the source of the clone. This does not apply to fields directly on the node.
