Hovercards (Extension:Popups) uses the title attribute of a link in an API query to get an extracts and thumbnail for a linked page. This works because when Linker.php turns a wiki link into HTML, it sets the title attribute to the namespace:title (getPrefixedText()).

However, Parsoid doesn't do this, it doesn't output a title attribute. Parsoid turns [[Talk:Main_Page]] into something like:

<a rel="mw:WikiLink" href="./Talk:Main_Page" data-parsoid='{"stx":"simple","a":{"href":"./Talk:Main_Page"},"sa":{"href":"Talk:Main_Page"},"dsr":[6,24,2,2]}'>Talk:Main_Page</a>

Hovercards may soon change to parsing the href contents. But this difference from Linker output may affect other gadgets and tools.
