The problem occurs at least on Polish and German Wikipedias. When
viewing a diff, categories and interlanguage links are not displayed in
the article preview below the diff. See [1] for an example.
According to the guys reporting it at the Polish village pump ([2]), the
issue appeared a few days ago and might have coincided with the recent
FlaggedRevs update.
Could you have a look at it?
Thanks in advance,
