### Steps to reproduce

* this is unclear, but it looks people are working on documents and saving them, not realising that they are not actually saved


### What is the buggy behavior?

* contents are not actually saved and instead the literal `undefined` is stored, e.g. for wiki pages, document contents or work package descriptions

* presumably it still looks as if the content has been saved, however


### What is the expected behavior?

* that should not happen
