@Jdlrobson what tasks related to ULS are within your team’s remit? If the answer is ‘none’, that is extremely poor given that your skin makes using ULS a requirement.

This is an issue with all skins, right? Not just Vector 2022 - so this needs to be fixed in the UniversalLanguageSelector extension. No team has picked this up but typically web team or/and language team work on UniversalLanguageSelector tasks (with language team the owner and point of first call).

I added this ticket to consider for the future re-implementation of the language selector with new frontend standards (T287860).
For this kind of issue where the main workflow is not affected (selecting a language leads to a page refresh), efforts seem better spent on the new version. But feel free to share other perspectives.

Well, it is an accessibility issue in the component that is currently forced on readers and editors on the default skin on most wikis, so I don’t think this should be fixed as some sort of medium-term goal. Same as T282024: ULS language list should use `column-width` CSS property instead of splitting the lists btw. (I should really collect the blockers to new Vector deployment somewhere already...)
