 * We load http and https pages and verify that scheme relative sources
 * are allowed unless its a downgrade from https -> http.
 *
 * Please note that the policy contains 'unsafe-inline' so we can use
 * an inline script to query the result from within the sandboxed iframe
 * and report it back to the parent document.
