Thanks _tarik_, your solution worked for me well!
I bumped into another problem when this started to work: https://www.drupal.org/project/draggableviews/issues/3408185 🐛 Save order button removed if bulk operations in view (by claro) Active , but I think it actually is a seperate issue

The patch worked for me as well, but only when using the Action dropdown and Apply to selected items button combination. It doesn't work when using the Display selectable actions as buttons option in the view VBO config.
