I consider this lowest priority because it only appears to happen after history merging.

Other variants on the logs (so they can be searched on phabricator):

"Format text/x-wiki is not supported for content model javascript"
"Format text/javascript is not supported for content model css"

I found another slightly different case editing this page: https://fi.wikisource.org/w/index.php?title=K%C3%A4ytt%C3%A4j%C3%A4:Hunsvotti/Gadget-Wikiviite.js&action=edit

Seems to happen after moving as well. See https://es.wikipedia.org/w/index.php?title=MediaWiki:Citoid-template-type-map.json&action=history and https://es.wikipedia.org/w/index.php?title=MediaWiki:Citoid-template-type-map.json&action=edit&oldid=81349374&debug=true
