Currently, page previews displays multiple paragraphs from an article. When switching to the html endpoint, this caused a series of style issues.
= Acceptance criteria
Change page previews to display only lead section of an extract
Note: "lead" will be defined as it was when switching the first paragraph above the infobox on mobile and include the first paragraph plus any following non-paragraph elements (for example: https://en.wikipedia.org/wiki/Planet should display the list following the first paragraph)
= Signoff criteria
After change is implemented, update https://www.mediawiki.org/wiki/Beta_Features/Hovercards with expected behavior (Olga)
