Use pipeline badges to indicate pipeline status in related merge requests UI in an issue.
The new related merge requests UI in an issue looks thusly (https://gitlab.com/gitlab-org/gitlab-ce/issues/47007).
The red x
circles toward the right represent pipeline status, but it could be confusing since people may think it's a button that you can click to remove the relationship, which is ill-defined (you can't remove this relationship manually).
Suggestion from @annabeldunstone : Use the badge for larger screens and just the icon for smaller screens:
