TYPO3 Core

This is a follow-up of #100030 , as the proposed patch there does not fix the problem.

thanks for taking care. Unfortunatly the proposed patch in #100030 still does not solve the problem. The backend users language still has an influence on the frontend translations (tested with dev-main with the patch already merged. I cross-checked the named files that the adjusted code is present.

Backend user with chosen backend language "english" sees english language labels in the frontend. If no backend user is logged in, or the chosen backend language is "german" the same labels are translated with the german version. The same thing occurs vice-versa if looking the engl. version of the FE page, but the admin has chosen "german" as backend language.

I still expect that the chosen language of the backend (!) user has absolutely no influence of the chosen language in the frontend.
