**Steps to replicate the issue** (include links if applicable): * Go to any special page with namespace selector with language variants ** For example, Special:AllPages: https://zh.wikipedia.org/zh-tw/Special:AllPages * Test 1: Check the option labels in the namespace selector with JavaScript disabled * Test 2: Check the option labels in the namespace selector with JavaScript enabled * Test 3: Try to execute `mw.widgets.NamespaceInputWidget.static.getNamespaceDropdownOptions( {} );` in console **What happens?**: * Test 2: The language variant namespace names unexpectedly replaced by canonical namespace names. * Test 3: The cause (the returned result didn't contain any information about language variant namespace names) * When JavaScript being enabled, it made the language variant namespace names unexpectedly replaced by canonical namespace names. **What should have happened instead?**: * Test 1: Expected options * The namespace names should show in the variant, like what it shows without JavaScript * `resources/src/mediawiki.widgets/mw.widgets.NamespacesMultiselectWidget.js` should use language variant namespace names instead of changing them to the canonical namespace name * `resources/src/mediawiki.widgets/mw.widgets.NamespaceInputWidget.js#L44` should give information about language variant namespace names **Software version** (skip for WMF-hosted wikis like Wikipedia): * MediaWiki: ** 1.41.0-alpha ( 4141cc4 ) ** 1.42.0-wmf.4 ( de18cff ) **Other information** (browser name/version, screenshots, etc.):
