Label link when filtering labels leads to 404 page
To reproduce:
- Go to https://gitlab.com/gitlab-org/gitlab-ce/merge_requests?label_name%5B%5D=Frontend
- Click the "Frontend" label
- You'll be taken to https://gitlab.com/gitlab-org/gitlab-ce/labels/127616, which 404's
I don't think we have a show
view for labels, so no page would exist for that route. Should we have one, or should we change/remove the link?
