@Iniquity -- thank you for reporting this.

@Trizek-WMF -- could you please figure out what is going on here and tell us what you recommend for next steps?

It seems that nstab-user is not gendered while on the homepage.

I checked on other messages, but I can't find any that's supposed to be gendered (from languages I know), so I can assess if it is a on-message issue, or if it is an overall gender issue on the Homepage. This needs further investigation with tools I don't have, hence passing it to @Etonkovidova.

Thanks @Iniquity for filing the bug - the issue is confirmed.

When Homepage is enabled - the 'User page' label (nstab-user) will not reflect a user's selected preference of being described as "she".

The animated gif below illustrates what @Iniquity described in the task description - switching between tabs displays either in Russian "Участник" - a masculine noun (the default option) or "Участница" - a feminine noun.

• ruwiki
• frwiki
• srwiki
• plwiki

Not sure about arwiki since there are several variants of Arabic scripts and only some of them user gender support for the 'User page' label.
Moving to Ready for Development.

The message for the talk page tab is {{GENDER:{{ROOTPAGENAME}}|Участник|Участница}} which is a horrible hack we cannot reasonably support. This needs to be fixed in core. The relevant task is T47938: Enable GENDER support in MediaWiki:Nstab-user.

@Etonkovidova could you please also check on some non-Growth wiki that nothing weird happens with the gendered user tabs? The work included a core change.

@Tgr - I don't see the fix working in betalabs ruwiki. It wasn't deployed there?

Code is always deployed to betalabs within a few minutes of being merged. I'm not sure when the localization cache gets rebuilt though, that can't possibly be happening after every puppet run.

I forgot to mention in my above comment - I checked bewiki, dewiki, and eswiki.
bewiki - User page name doesn't change when a gender preference is changed.
But
dewiki and eswiki - correctly reflect a gender preference in User page name.

@Tgr - I'm not completely sure whether there is a real issue for bewiki. Changing the gender preference does not even change the wording on the Special:Preferences page itself. Belarusian wiki has two variants - bewiki` and be-tarask.wiki.
be-tarask.wiki corectly reflects the gender preference a title of 'User' page, but not on Special:Preferences page. There is a chance that for bewiki it's completely correct (I don't know Belarusian language).

I checked Serbian (since there are also two lang variants - sr and sr-cyrl), but for Serbian lang variants there are not two wikis, but only lang preference.

Thanks for checking! be translation of "user page" is indeed not gender-dependent.
