--- Comment #4 from John Mark Vandenberg jayvdb@gmail.com --- The change for this bug was merged three weeks ago. Maybe labs only updated their code 5 days ago?
I'll try harder to reproduce it tomorrow, and provide a fix when I do.
I had a patch that probably fixed this, and other bugs, but it wasnt being reviewed for a week, so I started splitting it up. https://gerrit.wikimedia.org/r/#/c/143038/
