 * Parses the HTML fragment and sets it as the contents of this element.
 * This ensures that the generated content follows the sanitization rules
 * specified by the validator or treeSanitizer.
 * The resulting tree is guaranteed to only contain nodes and attributes
 * which are allowed by the provided validator.
 * @description Checks that if validator and sanitizer are omitted,
 * unknown elements and attributes are removed from provided html.
