Steps to reproduce

1. Create two users "user1" and "user2".
2. As "user2" share a folder "test" with "user1"
3. Login as "user1"
4. Create a file "versions.txt"
5. Edit and save the file multiple times to create versions
6. Check the versions dropdown for versions
7. Move the file "versions.txt" into "test"
8. Check the versions dropdown for "test/versions.txt"

Expected result

Versions preserved

Actual result

Versions not preserved. The version files are still in the home of "user1"

@DeepDiver1975 @karlitschek please evaluate severity. I'll set to 8.1 for now but we might want to have this earlier.

8.1 is fine
