Top 'Close Issue' Button not Working - 304 Status

Summary

It seems that the top "Close Issue" button is not working as expected. When clicking the "Close Issue" button, you can see a visual indication that it has been clicked, but nothing happens. When checking Kibana, you can see that 304 status is returned for the action. If you refresh the page, and attempt to click again, the result is the same. The bottom Close Issue button seems to work just fine, and quick actions like /close seem to work just fine as well.

This has been replicated on a customer project, personal project, as well as in a support team project.

Steps to reproduce

  1. Create a new issue
  2. Attempt to close it using the top Close Issue button. Note how it does not do anything.
  3. Refresh, attempt to close it again. Note the result is the same.
  4. Attempt to use the bottom Close Issue button. It should work without issue.
