Thanks for reporting this @Lmorillas. While I try to figure out why Popups is misbehaving, could you update the New Page to the following WikiText and test again?

Vivamus scelerisque congue arcu, ac viverra purus ullamcorper ut. Etiam at euismod elit. Sed pharetra bibendum sodales. Vivamus sollicitudin augue et lorem faucibus sagittis. Pellentesque habitant morbi tristique senectus et netus et malesuada fames ac turpis egestas. Pellentesque euismod felis ante, eget accumsan ligula eleifend non. Pellentesque viverra lectus ac magna malesuada porttitor. Lorem ipsum dolor sit amet, consectetur adipiscing elit. Aliquam consequat dolor auctor facilisis fringilla. Pellentesque dictum elit bibendum, faucibus purus a, tincidunt nisl. Integer mauris augue, interdum vel arcu ac, aliquet egestas ante. Ut ut accumsan lacus. Nam dolor leo, rhoncus id lobortis ac, luctus eget tortor.

== New Page ==

New page for testing

* New page for testing

Done, @Prtksxna It works now.

Updating New Page seems to have helped -

Hovercards requests TextExtracts to get text only from the intro section of the page. So, if there is no text before the first section, nothing is returned and it does not render a Hovercard.
However, in such a case, it should not be emptying the title. I'll work on a fix.

I don't know if it's the same issue, but Popups doesn't expand the templates. See [1].

That is definitely intended behavior. Popups is meant to quickly look at the intro text of a page, it does so using the TextExtracts extension. You can write new renderers for Popups to display different kinds of information from a page, but it doesn't support this template expansion right now.

Change 205638 had a related patch set uploaded (by Prtksxna):
Stop emptying link title if a TextExtract was not returned

https://gerrit.wikimedia.org/r/205638

Maybe it should be documented better this hovercards behaviour. I did read nothing before about this "Hovercards requests TextExtracts to get text only from the intro section of the page".

Thanks, @Prtksxna Is it documented how to write a new renderer for Popups? I'll investigate.

Sorry for the lack of documentation. I have updated Extension:Popups now.

Its not documented in depth, but I've added a new section in Extension:Popups that has some useful links—

Patch is -1ed but should be simple to fix up.

Thanks @Prtksxna Some feedback for you on the patch.

@Prtksxna still hoping for a response! Keen to get this off the backlog!
