This seems to relate to T275147.
UniversalLanguageSelector is adding a hidden element .uls-after-portlet-link which stops it being an empty portlet. I'm not sure under what conditions it should show.

Presumably, this should not be added if the cog is not present?

I'm seeing this on https://en.wikipedia.beta.wmflabs.org/wiki/Special:UserLogin:

Not sure if this is correct behaviour or not?

I don't think ULS is causing the extra whitespace, so we are not going to investigate that. "In other languages" section should only appear in wikies where $wgULSPosition = 'interlanguage' and when not using vector-2022.

Removing team tag after triage, but I have added this to Localization Infrastructure request list to be considered for future sprints.

This ticket is a few months old. There is no "In other languages" as of today.

It's at the bottom right now on the home page:

and in the header on normal pages:

Does office wiki have languages, or do we just need to disable this?
If it does, we should decline this ticket.
If it doesn't, I don't know if it's possible to disable the "add languages" feature. If not, perhaps we need that?

I think the article language selector should only be visible in the following cases:

• If there are inter-language links that need to be displayed
• If the page currently being displayed is a translatable page. This menu options listed can be updated the languages to which this page has been translated with an option to make further translations.

The interface language selector is still visible at the top of the page so no point having the "Add languages" trigger visible in that case.

A comment from @Pginer-WMF summarizing our discussion regarding expected ULS behavior in monolingual wikis:

• The selector on the user toolbar is for UI language (also setting the default language for content).
• For pages available in multiple languages, we may want to present the current list of languages as a ULS selector. Making content language selection consistent with how is presented in Wikipedia, and the actions related to it (i.e., translate to more languages with Translate)
• For pages not made available in multiple languages yet (but where it is possible to do so) we have to decide how much to emphasize/encourage making those translatable. Based on that present a prominent “Add languages” or a more discrete icon-only option to let people make the page translatable.

Some more context about why we're seeing this issue.

With this patch: 817894: Limit ULSPosition check to non-Vector 2022 skins | https://gerrit.wikimedia.org/r/c/mediawiki/extensions/UniversalLanguageSelector/+/817894 in Vector 2022, the lang portlet always has the empty span uls-after-portlet-link even if the ULSPosition is NOT interlanguage.

Now if a portlet is empty, then the SkinComponentMenu (https://github.com/wikimedia/mediawiki/blob/master/includes/skins/components/SkinComponentMenu.php#L95) in MediaWiki core will add an emptyPortlet class to the portlet section. The emptyPortlet class hides the entire portlet section. After the above patch, Vector 2022 the p-lang portlet is never empty and hence In other languages is visible whereas for other skins the emptyPortlet class gets added and hides it.

If I remove the code added in the patch, the issue is fixed but it screws up ULS when the Add Language / Language selector is displayed in the Vector header.

Change 932446 had a related patch set uploaded (by Jdlrobson; author: Jdlrobson):

[mediawiki/extensions/UniversalLanguageSelector@master] Display the language button on pages without languages

https://gerrit.wikimedia.org/r/932446

It seems like the language button disappears from the bottom of the page if there are zero languages - meaning there is no longer a way to switch languages. See https://he.wikipedia.beta.wmflabs.org/wiki/Main_Page for example.
Language button has disappeared from user pages: https://en.wikipedia.beta.wmflabs.org/wiki/User:Jdlrobson

the hook returns before some important handling for when there are 0 languages.

This is possibly not a big deal (a it would mean inability to switch language on user page - not sure if that's a big deal), but marking this as as a deploy blocker for your consideration.

A few combinations with the latest patch from Job:

1. ULSPosition = personal on normal pages

2. ULSPosition = interlanguage with VectorLanguageInHeader = false on normal pages

3. ULSPosition = interlanguage with VectorLanguageInHeader = true on normal pages

4. ULSPosition = interlanguage with PageTranslationLanguageList = sidebar-only and VectorLanguageInHeader = false on translatable pages

5. ULSPosition = interlanguage with PageTranslationLanguageList = sidebar-only and VectorLanguageInHeader = true on translatable pages

6. ULSPosition = interlanguage with PageTranslationLanguageList = sidebar-fallback and VectorLanguageInHeader = true on translatable pages

Page having <languages> tag:

Page without <languages> tag:

7. ULSPosition = interlanguage with PageTranslationLanguageList = sidebar-fallback and VectorLanguageInHeader = false on translatable pages

I no longer see In other languages in the https://office.wikimedia.org/wiki/Special:BlankPage but do see an empty Languages section appear on the Main Page:

Seems like a problem with local wiki styles:

@Quiddity could you replace that line with . vector-main-menu-action-lang-alert-empty { display: none; } ?
