* 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
