Related branches not always showing up
Related branches are associated to the issue only by having a name that starts with the internal id of the issue. After using the "New branch" button a related branch will be shown in the issue, but this is only because the branch name starts with the internal ID. You can force an issue to show related branches without using the "New branch" button.
I want to verify if this feature is actually working as it should be. I ask this as I know plenty of cases where I have the issue ID in the branch, while it doesn't show up in the issue. See for example this issue https://gitlab.com/gitlab-org/gitlab-ce/issues/25011
