+// provided, the script requests to close the dialog and stops there. If wrong
+// PIN is provided, the request is repeated until the limit of 3 bad tries is
+// reached. If the dialog is closed, the request is repeated without considering
+// it a wrong attempt. This allows the testing of quota limit of closed dialogs
+// (3 closed dialogs per 10 minutes).

prefer just
if (chrome.runtime.lastError)

Done.
