+// Here's the set-up for this test:
+// Step 1 (top-frame) Set up listener for "HasAccess" message.
+// Step 2 (top-frame) Add data to first-party cookies.
+// Step 3 (top-frame) Embed an iframe that's cross-site with top-frame.
+// Step 4 (sub-frame) Try to use storage access API and read first-party data.
+// Step 5 (sub-frame) Embed an iframe that's same-origin with top-frame.
+// Step 6 (sub-sub-frame) Try to use storage access API and read first-party data.
+// Step 7 (sub-sub-frame) Send "HasAccess for cookies" message to top-frame.
+// Step 8 (top-frame) Cleanup.
