 * most editors get it implicitly; depend on it directly to get the
 * equivalent of the legacy core `importDOM` behavior for `<p>`,
 * `<span>`, `<b>`, `<strong>`, `<em>`, `<i>`, `<code>`, `<mark>`,
 * `<s>`, `<sub>`, `<sup>`, `<u>`, `<br>`, and `#text` (plus `<hr>`
 * when `HorizontalRuleNode` is registered).
