          "1. Add a QR-based hardware wallet (e.g., Keystone) via Add Hardware Wallet > QR and import an account.",
          "2. Send a small amount of ETH from that account; scan the signing QR with the device, then scan the device’s signature QR back into the extension.",
          "3. Verify the loading/progress view advances promptly to Submitted and then Confirmed without hanging.",
          "4. Repeat with an ERC-20 token transfer to confirm the fix covers token sends."

          "2. Verify the extension exits loading with a clear error and presents Retry/Cancel (or equivalent) actions.",

          "3. Confirm the transaction on the Ledger; verify the extension shows the correct prompts and transitions from Pending to Confirmed.",
