Translatable entity reference fields are not cloned correctly

The patch proposed for this issue is very similar to the patch #40 at #3050027.

Any chance we can get this merged? This has caused my company major headaches, data loss for multiple clients. Pretty much every site using translations + entity clone has this problem.

I found another issue: the clone form says Circular reference detected for paragraph fields if the entity has a translation. This happens because both translations of the entity share the same paragraph ID, but a different translation.

Steps to reproduce

I'm assuming a site with two languages, EN and FR.

1. Create an EN article called 'Test', with 1 text paragraph.
2. Translate the EN article to FR, both the node title and the paragraph text
3. Visit the clone form of the FR translation of the article. It will show Circular reference detected under the paragraphs field
4. If you clone the node, the paragraph will not be cloned and both nodes will share the same paragraph, which normally shouldn't be possible.

I opened a new branch/MR which is rebased against 2.x.

I've resolved merge conflicts with 2.x and have tested this along with the change from Issue 3050027 🐛 Inline Blocks on Layout Builder Fail to Clone Correctly Needs work mentioned in #12. 3050027 alone didn't fix the issue for me so this is still needed. We're using paragraphs_asymmetric_translation_widgets in our setup, for what it's worth. We also encountered data loss with this so would be grateful to see a release with both fixes.

Patch in #18 seems to solve the issue. I think it is a major issue because it will cause data loss if you happen to delete one of the nodes.

Verified MR!52 and and seems it works as expected, hence requesting review as I have made changes in the MR.
Meanwhile will look into failing tests.

It seems like there might be some similar work happening in 🐛 Inline Blocks on Layout Builder Fail to Clone Correctly Needs work .

I tried the patch from 3258535-2.x-translatable-entity-reference and fixed my problem of translated entities wrongly cloned when translated from an entity that is not the master of the translations.

Hi I applied 3258535-2.x-translatable-entity-reference patch, but as we have many nested node I'm experiencing
Allowed memory size of ... bytes exhausted. I would love to get rid of the checkboxes form or have option to disable it as we are cloning everything. I will check if I can find some walk-around ...

Alright, it looks like I have a working patch for version 2.1.0-beta1. I've attached the patch for you. I tested it, and it resolves the issue with sub-nodes not having translations properly attached. Please give it a try.

I'll also be preparing a separate patch for the 2.x branch shortly.

Ok I prepared patch for 2.x but something is wrong here I can not see a way to created a PR, so please have a look at https://git.drupalcode.org/issue/entity_clone-3258535/-/compare/2.x...32...
