// Step 1 (top-frame) Set up listener for "HasAccess" message.
// Step 2 (top-frame) Add data to first-party cache storage.
// 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 estimate 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 estimate first-party data.
// Step 7 (sub-sub-frame) Send "HasAccess for estimate" message to top-frame.
// Step 8 (top-frame) Receive "HasAccess for estimate" message and cleanup.
