##### SUMMARY
ansible_run_tags documentation says the default is empty ("[]") at https://docs.ansible.com/ansible/latest/reference_appendices/config.html#tags-run

However when running a debug print with no tags specified, we get this output:

```
- name: print tags
  debug:
    msg: "{{ ansible_run_tags }}"
```

```
$ ansible-playbook deploy.yml
```

```
