* Description of the test:
* 1) Let's load a form into an iframe which uses a CSP of: form-action 'none';
* 2) Let's hit the submit button and make sure the form is not submitted.
*
* Since a blocked form submission does not fire any event handler, we have to
* use timeout triggered function that verifies that the form didn't get submitted.
