Creating Tag does not trigger build

Summary

Gitlab CI is not queuing builds for tags. I have included .gitlab-ci.yml, which was working properly on 8.2.x, but is not on 8.3.0

Steps to reproduce

Create a project with the specified .gitlab-ci.yml file. Create a branch called production make at least one commit on that branch.. Create a tag from the tip commit of production.

Expected behavior

I expect a build to queue for the tag. On 8.2.x, it would queue up a Test build for the tag, and then if the test passes it would queue up a Deploy Production build. Now creating a tag does not queue up any builds at all. This is possibly because of the "except production" markup, though on previous versions of Gitlab creating a tag would still trigger a build, even if the tag was on a commit in the production branch.

Relevant logs and/or screenshots

#.gitlab-ci.yml
Test:
  script:
    - fab test
  except:
  - production

Deploy Staging:
  script:
  - fab deploy_staging
  type: deploy
  only:
  - master

Deploy Production:
  script:
  - fab deploy_production_web
  - fab deploy_production_worker
  type: deploy
  only:
  - tags
