Same problem here. It seems to me this was caused at https://gerrit.wikimedia.org/r/c/mediawiki/core/+/1037742/1/resources/src/mediawiki.diff.styles/diff.less#b268 during T365759 (@Volker_E).

Doesn't seem to be skin specific. Also impacts Monobook and Timeless:

https://en.wikipedia.org/w/index.php?title=Wikipedia:Sandbox&diff=prev&oldid=1227609467&safemode=1&useskin=timeless

There are no recent changes to diff code or https://gerrit.wikimedia.org/r/q/projects:mediawiki/php/wikidiff2
Which points to styling.

I ran git bisect and identified https://gerrit.wikimedia.org/r/c/mediawiki/core/+/1037742 as the culprit.

(Just for reference: ⚫ is in code because of T176485.
Per Jdlrobson’s investigations, this issue is a regression from MW-1.43-notes (1.43.0-wmf.8; 2024-06-04).)
