The post id 34dead42a28 contained a new paragraph type: H2. Previously
the only known header types were H3 and H4. In this case, the paragraph
doesn't actually get rendered because it's the page title which is
removed from the page nodes (see commits 6baba803 and then fba87c10).
However, it somehow an author is able to get an H2 paragraph into the
page, it will display as an <h1> just as H3 displays as <h2> and H4
displays as <h3>.
