Both these pages output lang="qqq" which was flagged by Lighthouse as invalid. For items depicting Message Documentation, the language code of content language should be used.
Place to fix:
- lang attribute in SpecialTranslations::showTranslations
- lang attribute in SpecialSupportedLanguage::outputLanguageCloud
Make sure you have $wgTranslateDocumentationLanguageCode = 'qqq'; set in LocalSettings.php. Create for example a translatable page and add message documentation for it.
