// Here's the set-up for this test:
// Step 1 (top-frame) Set up fallback failure listener for if the handle cannot be used.
// Step 2 (top-frame) Set up relay worker to expect "Same-origin handle access".
// Step 3 (top-frame) Set cookies and embed an iframe that's cross-site with top-frame.
// Step 4 (sub-frame) Try to use storage access API to access shared worker.
// 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 to access first-party shared worker.
// Step 7 (sub-sub-frame) Send "HasAccess for SharedWorker" message to top-frame.
// Step 8 (top-frame) Set up cookie worker to expect it's already opened.
// TODO(crbug.com/1484966): Verify access to cookies in shared workers.
