Generally: it looks like this is an old bug (at least 2015), per
https://phabricator.wikimedia.org/T102888 ("[Bug] Recent changes pages
doesn't have anymore the interlingual wikilinks on the sidebar on some
projects")
and connected tasks.
Specifically: A newer bug, which might be why things have recently
changed at zh-yue, is
https://phabricator.wikimedia.org/T172461 ("Special:RecentChanges no
longer displays interwiki links on wikis that have added them to
MediaWiki:Recentchangestext")

An editor on the Cantonese Wikipedia has noticed that
Special:RecentChanges
has stopped displaying interwiki links. Is that a permanent, deliberate
change? And if so, is it possible for an individual editor to re-enable the
display of interwikis on such special pages?
