TYPO3 Core

Way to reproduce:

- Create a new content element containing a FAL relation field.
- add a file
- edit the file and add some meta data like title, alt and description
- translate the file (meta data) and fill up translation content for those fields (this two steps could also be done before within the File module)
- translate the content element
- now the file meta data of the translated content shows default language content in sys_file_metadata fields

Some Backgrounds:
- this was testet with a plain installation and official introduction package installed
- TYPO3 10.4.21 shows the correct translated field contents
- TYPO3 11.5.1 shows field content of default language in translations

Maybe Related:
- In a client project (TYPO3 10.4.21) I have old content elements using flexforms - there the behaviour is also, that default language is shown in translations - but not in TCA field - there its correct translated.
