Hey guys! In another project, I recently had the same need of adding some user-supplied HTML. I came around this little snippet that will try to fix malformated HTML. Consider adding it to Hajk too, please!

/**
 * @summary Ensure that the supplied string isn't malformed by parsing it using the DOM.
 * @description Please note that this function doesn't do any actual sanitizing, hence "pseudo".
 * @param {string} html
 * @returns
 */
export function pseudoSanitize(html: string) {
  const doc = document.createElement("div");
  doc.innerHTML = html;
  return doc.innerHTML;
}

And in another file, where pseudoSanitize is imported, just do:

           <div
            dangerouslySetInnerHTML={{
              __html: pseudoSanitize(userInputWithHtml),
            }} 
            />

Absolutely! Very useful snippet

Should we merge without adding Jacobs function?

LGTM. Lets add Jacobs stuff later in another issue.
