Form: focus style missing
The current form sketch design is missing focus styles: https://gitlab-org.gitlab.io/gitlab-design/hosted/design-gitlab-specs/forms-spec-previews/
This lead to some confusion on how to handle invalid inputs, with a focus. See discussion in MR !1171 (merged)
I also noticed that focus styles change on different sites. See MR: !1165 (merged)
I think it might be worth it to add focus styles to the style documentation, and also add specific focus styles to GitLab UI
