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.
