Typing in single Job Tags or comma-separated multiple Job Tags in the Job Tags field of the Plugin don't pass through to the corresponding AWX/Ansible Tower Job Template. The other fields like limits and extra vars, however, have been tested to work okay.
Tasks should be limited to run based on their specific job tags.
The entire playbook is running, with the job unaware of job tags being specified.
Note: Job Tags specified directly in AWX Job Templates will run the tasks as expected.
