TYPO3 Core

Given:

- system with at least two languages
- install the attached extension
- create a new page and translate into another language
- create a new content element "copy_irre" and attach a child link
- translate the content element into the other language
- change the link label of the translated child link
- copy the content element and paste it anywhere on the site

Expectation:

- a copied content element should be visible
- the label of the translated child should match the original translation

Actual:

- the original link gets synchronized again, the label gets lost

It seems the correct translation is created first but gets deleted again and a new synchronization is created.

The copy & paste steps work correctly if the allowLanguageSynchronization is turned off.
