To do this, we'll need (in abstract mode when the target is an AW page) to (if the WikibaseClient extension is available), get an EntityLookup via the ClientStore and use it to get the label of the item in our language.

Very rough code from semi-memory and semi-looking-at-what-we-did-in-WikifunctionsPFragmentHandler:

if ( !ExtensionRegistry::getInstance()->isLoaded( 'WikibaseClient' ) ) {
	return false;
}


// Note: This line should be done once in the constructor
$wbEntityParser = \Wikibase\Client\WikibaseClient::getEntityIdParser();

try {
	$itemId = $wbEntityParser->parse( $qid );
} catch ( \Wikibase\DataModel\Entity\EntityIdParsingException ) {
	// Not a valid Wikidata reference
	return false;
}

// Note: This line should be done once in the constructor
$wbEntityLookup = \Wikibase\Client\WikibaseClient::getStore()->getEntityLookup();

$wbEntity = $wbEntityLookup->getEntity( $itemId );
$labels = $wbEntity->getLabels();
…

Hope this helps.

TY @Jdforrester-WMF do you think it makes sense to implement this logic into onHtmlPageLinkRendererEnd()
