Thanks. It looks like the errors are coming from de.wikipedia, en.wikipedia, and fr.wikipedia, so it's probably something in the Wikimedia CH banners. I'll take a look.

This was a reoccurence of T281547 (or at least the OG version of that task which was related to banners). We cloned the 2021 Wikimedia CH banners from an older version which didn't have the fix for that, I've now applied the fix to all of them so the errors should dry up.
