Related merge requests not showing up in issue

Summary

Related merge requests are not showing up in issues in our omnibus installation. You can see that the MR was created in annotations A & B (image below), but there is not corresponding merge request link at annotation C.

I've tried in existing and new projects with existing and new issues and it occurs everywhere. I have created the MR both from the default and specific branches and it occurs on both. This bug is not present on gitlab.com from what I can tell.

Steps to reproduce

Bring up a self-hosted version of GitLab Omnibus (via Docker)

docker-compose.yml 
version: '2'

networks:
  gitlab:

services:

  gitlab:
    container_name: gitlab
    image: gitlab/gitlab-ee
    restart: always
    hostname: example.com
    ports:
      - '80:80'
      - '443:443'
      - '2222:22'
    volumes:
      - ./data/gitlab/config:/etc/gitlab
      - ./data/gitlab/logs:/var/log/gitlab
      - ./data/gitlab/data:/var/opt/gitlab
    extra_hosts:
      - example.com:172.16.0.1
    networks:
      - gitlab

  gitlab-runner:
    container_name: gitlab-runner
    image: gitlab/gitlab-runner
    restart: always
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
      - ./data/gitlab-runner/config:/etc/gitlab-runner
    extra_hosts:
      - example.com:172.16.0.1
    networks:
      - gitlab
 
  • Create an issue
