+If the resulting HTML is a single paragraph, Hugo removes the wrapping `p` tags to produce inline HTML as required per the example above.
+
+To keep the wrapping `p` tags for a single paragraph, use the [`RenderString`] method on the `Page` object, setting the `display` option to `block`.

+Although the `markdownify` function honors [markdown render hooks] when rendering markdown to HTML, use the `RenderString` method instead of `markdownify` if a render hook accesses `.Page` context. See issue [#9692] for details.
