Not all assignees are visible in dropdown in assignee sections
Problem
- Not all assignees are visible in dropdown in assignee sections
see https://gitlab.com/gitlab-org/gitlab-ce/issues/33409 for testing
Solution
- All assignees should be visible and stacked in the "Assignee(s)" section, not just the first one.
- Assignee sections should be called
Assignee(s)
