### Issue description

Trying to move a folder results in moving error and it's not moved.
Regression from #75330

A fix already exists, but I'm opening an issue so it's not lost (the PR isn't ready and not very active).

### Steps to reproduce

1. Add 2 folders in filesystem
2. Move one folder into another one

### Minimal reproduction project
