Mentioned in SAL (#wikimedia-operations) [2020-04-02T18:22:08Z] <urbanecm@deploy1001> Synchronized php-1.35.0-wmf.26/extensions/VisualEditor/modules/ve-mw: SWAT: rEVED94ded03cd479: Fix issues with treating section "numbers" as integers (T248795; T248968; T249112) (duration: 01m 10s)
The bug affects wmf.25 and wmf.26. I only backported it to wmf.26, because the patch did not cherry-pick cleanly to wmf.25, and I didn't want to make last-minute changes to it. wmf.26 should be deployed everywhere in a few hours.
I can confirm the issue is not present with the current version of MediaWiki software on itwiki.
