 * Browsers don't offer a way to check if something is a public suffix
 * e.g. `.com.au`, `.io`, `.org.uk`
 *
 * But they do reject cookies set on public suffixes
 * Setting a cookie on `.co.uk` would mean it was sent for every `.co.uk` site visited
 *
 * So, we can use this to check if a domain is a public suffix
 * by trying to set a cookie on a subdomain of the provided hostname
 * until the browser accepts it
