+/* Description of the test:
+ * We have two tests where each tests serves a page using two CSP policies:
+ *   a) * default-src 'self'
+ *      * default-src 'self' 'unsafe-inline'
+ *
+ *   b) * default-src 'self' 'unsafe-inline'
+ *      * default-src 'self' 'unsafe-inline'
+ *
+ * We make sure the inline script is *blocked* for test (a) but *allowed* for test (b).
+ * Multiple CSPs should be combined towards an intersection and it shouldn't be possible
+ * to open up (loosen) a CSP policy.
