 * Description of the test:
 * 1) We load an iframe which tries to set a same site cookie using an
 *    inline script in top-level context of http://mochi.test.
 * 2) We load an iframe from http://example.com and check if the cookie
 *    is available.
 * 3) We observe that:
 *    (a) same site cookie is available in same origin context.
 *    (a) same site cookie has been discarded in a cross origin context.
