**Steps to reproduce:**
* Look at the list of languages e.g on https://test.wikidata.org/wiki/Special:NewItem
**What happens?**
`mul` can be found at the very end of the list.
**What should have happened instead?**
`mul` should be found at the position defined by sorting by language code.
**Notes:**
* In T329626 we wanted the list of languages sorted alphabetically (including "multiple languages"). We decided to split this task out from the original task.
* Lucas started a patch https://gerrit.wikimedia.org/r/c/mediawiki/extensions/Wikibase/+/901555
**Notes about the status quo:**
The list is currently a union of MediaWikiContentLanguages and additional StaticContentLanguages
The list of term language codes is:
* all codes supported by MediaWiki core
**MediaWiki ensures this list is sorted
**only in production, this also includes agq, bag etc., via wmgExtraLanguageNames
*a hard-coded extra set of language codes: agq, bag, etc.
**this list is sorted in the source code
*mul, if enabled
So on production Wikidata, the second and third list item make no difference; on a default Wikibase, the third list item has no effect, but agq/bag/etc. will be after the regular language codes; on Test Wikidata, the second list item makes no difference (redundant), but the third list item adds an unsorted language code at the end.
**Open questions:**
* Sarai wanted to sort the list alphabetically by the language name, originally. Would sorting by language code be good enough? It would have the advantage that it is only one order for all UI languages.
* Manuel plans to keep the status quo for now: MUL is also sorted last in the termbox, so maybe this position is intuitive in the list as well. This is why this task is out of scope for the "Improved Language Fallback (MUL)" initiative (see "Out of Scope" section in the epic T312097).
**Acceptance criteria:**
[] We understand the problem that leads to this issue.
[] The problem is solved (or if solving the problem is out of scope, then please create a follow-up task,The languages are sorted alphabetically / by language code (TBD). so we can discuss it).
