BUG: Workspace changes not visible in translations

[Rall3n]

Yes

I have checked that there are no already open issues or recently closed issues about this bug
Yes

Describe the bug
When editing a workspace record in a translation page, the changes of the workspace record are not reflected in the frontend. Non-translated pages don't show that issue.

To Reproduce
Steps to reproduce the behavior:

1. Create a page and a translation with one Flux-powered content element with at least one defined field.
2. In a workspace edit the translation of the content element.
3. Preview workspace version of record and see changes not reflected.

Expected behavior
Changes on the workspace record are reflected in frontend.

Screenshots

Additional context
The problem originates in Classes/Controller/AbstractFluxController->getRecord(), where the record data from the ContentObjectRenderer, which at this point is fully overlayed, is being overwritten with the data of the language record.
