I've reported this previously by email to @MMiller_WMF and @Trizek-WMF, which was later forwarded to @kostajh. Kosta said the issue should be fixed by 73a68b2ae325487077df9b274b47057a767b9247 (he also said I should have a look at depends-on for that page, which is 038c312cd4f04edeefb8eefb26009dbd10cb3846).
However, it seems to either not start to work at all, or be broken again. Any ideas?
