Comment:

 The original patch here breaks referer URLs from different query
 variables, and also doesn't account for URLs from the different servers,
 but (coincidentally) the same resource.

 If we use get_site_url() in wp_get_referer() for comparison instead, it
 fixes this and accounts for query variables and different servers.

 I've also attached unit tests for this.
