<title>Bug 1073952 - Test CSP enforcement within iframe srcdoc</title>

/*
* Description of the test:
* (1) We serve a site which makes use of script-allowed sandboxed iframe srcdoc
* and make sure that CSP applies to the nested browsing context
* within the iframe.
* [PAGE WITH CSP [IFRAME SANDBOX SRCDOC [SCRIPT]]]
*
* (2) We serve a site which nests script within an script-allowed sandboxed
* iframe srcdoc within another script-allowed sandboxed iframe srcdoc and
* make sure that CSP applies to the nested browsing context
* within the iframe*s*.
* [PAGE WITH CSP [IFRAME SANDBOX SRCDOC [IFRAME SANDBOX SRCDOC [SCRIPT]]]]
*
* Please note that the test relies on the "csp-on-violate-policy" observer.
* Whenever the script within the iframe is blocked observers are notified.
* In turn, this renders the 'result' within tests[] unused. In case the script
* would execute however, the postMessageHandler would bubble up 'allowed' and
* the test would fail.
