// This test creates a form whose submission GETs the page
// (on the specified origin) in a popup window. The popup sends a postMessage
// event back to its opener (i.e., here) with the cookies it received, which
// we verify against expectedStatus. Then, the test sends a message to the
// popup, telling it to reload itself via window.location.reload(). Again,
// the popup posts a message back here with the cookies it received. These
// cookies are verified against expectedStatusReload.
