W3C advises that all [forms have submit buttons](https://www.w3.org/TR/WCAG-TECHS/H32). I guess we can also have this hidden / screen-reader only. This also means we can remove the button that we add only in CI environments. (https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/27795) ```ruby = button_tag 'Go' if ENV['RAILS_ENV'] == 'test' ```
