The formatted endpoint identifies the "intro" for an article. It seems this intro is ill-defined to include any element that is not a `p`
For example:
```
{
"intro": "<p>The following is a list of the <b>highest-grossing films in <a href=\"./China\" title=\"China\">China</a></b> (excluding <a href=\"./Hong_Kong\" title=\"Hong Kong\">Hong Kong</a> and <a href=\"./Taiwan\" title=\"Taiwan\">Taiwan</a>), based on data by Entgroup's China Boxoffice (CBO) website with the gross in <a href=\"./Renminbi\" title=\"Renminbi\">yuan</a>.<span class=\"mw-ref\" id=\"cite_ref-1\"><a href=\"./List_of_highest-grossing_films_in_China#cite_note-1\" style=\"counter-reset: mw-Ref 1;\"><span class=\"mw-reflink-text\">[1]</span></a></span></p><div>\n<dl id=\"mwCA\"><dd id=\"mwCQ\"><i>Background colour <span style=\"background-color:#ffff80; color:; border:1px solid #000000; text-align:center;\"><span> </span><span> </span><span> </span><span> </span></span> indicates films that are currently in cinema</i></dd></dl>\n</div>",
}
```
