The links to individual languages in the <languages /> tag from the page translation feature should have lang and or hreflang attributes. This would make it easier to e.g. apply CSS to certain languages, for example to highlight the official languages used on a wiki, or in user stylesheets to apply custom styling to languages of the user's choosing. The same should also apply to the span tag for the current language.
Thanks, I can reproduce now.
Sesms like it's from this file:
However no matter how I make changes there, I don't see the effects on the page.
For example on Line 264
$classes = 'mw-pt-languages-ui';
<span class="mw-pt-languages-ui mw-pt-languages-selected mw-pt-progress mw-pt-progress--complete">English</span>
If I change it to
$classes = 'lorem-ipsum';
I expect to find a class called lorem-ipsum on that page. But nope!
Is there any caching somewhere? I'm using the mediawiki vagrant, and it has been working great so far.
