Only reproducible in group0 wikis, this assuming this is a regression with wmf.2 and marking as a train blocker.
git bisect locally suggests aaf418b3c8; cc @Ammarpad @Ladsgroup fyi
Tagging MW-1.45-release as that commit was also backported to REL1_45 (and I've confirmed locally that this bug also seems to occur when on the release branch).
Change #1203855 had a related patch set uploaded (by Ammarpad; author: Ammarpad):

If there is no review soon, in my understanding rMWaaf418b3 is self-contained and can simply be reverted in order to unblock the deployment train?

I've pushed the revert on wmf.2 but haven't merged it on master. I don't have the capacity to review the fix patch so if someone else manages to do it, great. If not, then on Monday, I'll merge the revert on master.
Reverted https://gerrit.wikimedia.org/r/q/aaf418b3c8ac1990308cd149b8f6485740c496f6 via https://gerrit.wikimedia.org/r/c/mediawiki/core/+/1204258 in the wmf.2 branch only by Ladsgroup, thus resolving T409831, reopening T345793, and marking T345793 as a wmf.3 blocker.
Let's sort out how to proceed in reopened T345793; closing this very ticket.
