 * Description of the test:
 * 1) We load an image from http://example.com which tries to 
 *    a) a same site cookie
 *    b) a regular cookie
 *    in the 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 has been discarded in a cross origin context.
 *    (b) the regular cookie is available.
