+The `ignore` option accepts a query selector. If the
+[`node.matches`](https://developer.mozilla.org/en-US/docs/Web/API/Element/matches)
+returns true for that selector, the node will be ignored. This defaults to
+`'script'` because generally you don't want to select script tags, but if your
+content is in an inline script file, then the script tag could be returned.
+
+If you'd rather disable this behavior, set `ignore` to `false`.
