/* Description of the test:
This test makes sure adding a CSP directive to an
iFrame does not propagate
the new directive to the parent document.
The test page records it
's own CSP before and after adding an iFrame
with an additional CSP directive.
CSPs before and after adding the
iFrame are compared to make sure they do
not differ.
