Note to self: There's a patch here in case this crops up when 1.46.0-wmf.13 (T413804) rolls to all wikis.

ihurbain added a comment.Jan 29 2026, 4:10 PM

@brennen from our perspective, we expect some logspam, hopefully limited, but no other consequence (hence we haven't gone out of our way to backport this this week, because Parsoid backports are annoying). If logspam is problematic or if it has other consequences, don't hesitate to ping our American-timezoned team members :)
