Weird – I can see this on the wikidata-shex test system, but locally the language code is there.

That <h1> comes from MediaWiki itself, we are only handling its content. So this seems to be a configuration issue?

This is also broken on :/ ==> Adding campsite.

Turns out even is affected as this is a problem in the vector template. Patch coming.

The additional claim lang="..." should be entirely removed from the heading element.

It is confusing and pointless.

It is superfluous to provide explicitly a language attribution when it is better inherited from <body> or<html>.

Look at this example (viewing Tower Bridge in French Wikipedia by Portuguese UI):

<h1 id="firstHeading" class="firstHeading" lang="fr">Diferenças entre edições de "Tower Bridge"</h1>

The claim is entirely nonsense. Diferenças entre edições is Portuguese, Tower Bridge is English, and nothing is French as claimed.

It is more consistent to inherit from ancestor even if not correct in this place, than explicitly stating wrong information.

  • UI parts and special page names follow user language.
  • Content areas follow page language, falling back to site language.
  • Text fragments might be neither the one nor the other, as shown.

@PerfektesChaos I support you comments, but this task is the wrong place. This task is just for restoring the previous behavior after making a typo in the refactoring. This is solved and therefor this task is solved.

To solve your comments I already created and dependencies. This change needs to rebased, updated, refactored to a different class and tested with all supported browser.
