I noticed that recently the labeling gadget http://labels.wmflabs.org/ui/ has reversed sides for before and after diffs, except on cases when there is a new page creation. Looks like a bug. Can someone verify? I am doing good/bad rating on lvwiki tasks.
This is a vandalism: https://lv.wikipedia.org/w/index.php?diff=2674922 But on labeling page the "after" is shown in first column.
We're working on a bug fix deployment right now. It should be ready in a couple of minutes. It looks like 21 labels have been submitted since the bug was introduced. I'll be removing those. There will be an announcement going out soon.
Fixed. See https://phabricator.wikimedia.org/phame/post/view/69/wikilabels_incident_reversed_diffs/
Thanks again for reporting. Your timely notice was invaluable!
