Security researcher Jonathan Morgan reported that when a page loaded over an insecure protocol, such as http: or file:, sets its document.location to a https: URL which responds with a 204 status and empty response body, the insecure page will receive SSL indicators near the location bar, but will not have its page content modified in any way. This could lead to a user believing they were on a secure page when in fact they were not.
