/* Description of the test:
* The test is twofold:
* First, by loading a page using meta csp (into an iframe) we make sure that
* images get correctly blocked as the csp policy includes "img-src 'none'";
*
* Second, we make sure meta csp ignores the following directives:
* * report-uri
* * frame-ancestors
* * sandbox
*
* Please note that the CSP sanbdox directive (bug 671389) has not landed yet.
* Once bug 671389 lands this test will fail and needs to be updated.
