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, lampak
