Vector currently has 2 h1 headings - the default one and the Wikidata one. This will confuse web crawlers.
In mobile the heading shows twice because of this hack.
Please use onOutputPageParserOutput hook and set the page title like this instead to generate the headings:
$outputPage->setPageTitle( 'Universe <span>(Q1)</span>' );
