In Bug 1549973, we introduce a way to do the final tabState flush before closing the tab.
It can work successfully on the normal case.

However, we cannot complete the final flush when doing "await BrowserTestUtils.closeWindow(win);".

From the investigation, we found that BrowserChild uses "SendSessionStoreUpdate()" to send final flush. However, BrowserParent cannot receive this IPC call.

From the investigation, it seems that BrowserChild have sent the finsh flush by "SendSessionStoreUpdate()". However, BrowserParent cannot receive this IPC call.
