     10 // Here's the set-up for this test:
     11 // Step 1. (window) set up listeners for main window.
     12 // Step 2. (window) set up load listener for same-site iframe.
     13 // Step 3. (same-site iframe) loads, send it a message to createOrGet a "userID".
     14 // Step 4. (same-site iframe) receives the message, creates the "userID".
     15 // Step 5. (window) receives "storage got set" message from same-site iframe.
     16 // Step 6. (window) opens cross-site window w/ shared (same-site to us currently) iframe.
     17 // Step 7. (cross-site iframe) loads, sends back the userID key from the iframe.
     18 // Step 8. (window) asserts that the IDs should be different, as they should have a different StorageKey.
