Steps to reproduce

1. Go to Magnolia demo
2. Log in as superuser, go to Security App and edit the userrole "/travel-demo-tour-editor"
3. On the Access Control list tab set ACL for dam to "/tours" (Read/Write, Selected and sub-nodes)
4. Log in as tina
5. Go to Assets app and open "/tours" folder
6. Delete one of the assets
7. Publish deletion
8. Once the deletion has been successful, click on any of the checkboxes on the left column (e.g., on the /travel folder)
9. Check an error banner appears

If you click anywhere else, the error doesn't happen, it has the be a checkbox
an error banner with the error message "Access denied" appears, even though the deletion has been successful.

This happens, because there is a weird interaction with a deleted node directly under "/" at this point, please have a look.
