We're logging a lot of MediaWiki\Extension\VisualEditor\ParsoidHelper::transformHTML: Received funny ETag from client: https://logstash.wikimedia.org/goto/8ab916541d77393b7f2b438b9801e165
This is caused by https://gerrit.wikimedia.org/r/c/mediawiki/extensions/VisualEditor/+/826644, which was supposed to decrease the amount of logging for this. Oops.
