### Steps to reproduce

The steps are not yet clear. I failed to reproduce it locally or with my private project here on the community instance.

It also does not depend on the new rendering of the Activity tab. When we deactivated the feature flag we still observed the same behavior.

However, it is reproducible at its original place:

1. Here on community go to work package ##57107

2. Change the parent (add or remove)


### What is the buggy behavior?

* Check your own user's timeline (https://community.openproject.org/users/me) and see that the change of the parent affected many other work packages. It introduced new journal entries with  "_The changes were retracted."_


### What is the expected behavior?

1. It does not affect the other work packages.
