It seems it is working on only 1.19 wikis. Ex. it works on Community Wiki and Avatar Wiki (but still with the title indented), which have been hit by the upgrade, but on Trackers Wiki and Presidential Primaries Wiki, which have not been upgraded, are not working as before. It seems I will just have to wait for the upgrade to finish.
