Pull Request Checklist

• Have you read "How to write the perfect pull request"?
• Have you read the contributing guidelines?
• Have you added tests for any changed functionality?
  • I'm still new to contributing and wasn't sure how to add a test for this. Maybe some render_template thing? I didn't find any existing tests for _comment_actions, and this is my first time developing in ruby so I'm unfamiliar with the tooling.
• Have you added the Jira issue number
  as the first thing in your pull request title (e.g. AO3-1234 Fix thing)
• Do you have fewer than 5 pull requests already open? If not, please wait
  until they are reviewed and merged before creating new pull requests.

Good to see you again, Wanda!

We typically prefer to test changes to views in our integration tests. For small changes like this, the easiest thing to do is usually look around and see if there's an existing test you can modify. In this case, this scenario testing moderated comments in threads is probably a good candidate.

You can find some info on working with these tests on our Automated Testing wiki page, but if you have specific questions, please let us know!
