 Can you confirm my understanding of #6458?
 1. user visits https://thirdparty.com, gets HSTS pin
 2. user visits http://example.com with <img src="http://thirdparty.com">.
 the browser makes the request over HTTP anyway because the user has never
 visited thirdparty.com on example.com before.

 I think that would stop the Sniffly attack.
