| // 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 localStorage" message to top-frame. |
| // Step 8 (top-frame) Expect new data to be set and properly trigger listener. |
