I have javascript on page that asks the user for Save changes when page is closed? The saving includes submit on the same page. The saving mechanism works just fine when whole browser is closed, but when only a tab is closed the event onunload fires but the javascript does not submit the page.

Reproducible: Always

Steps to Reproduce:
1.Make javascript that submits the page
2.Call the script on page onunload event
3.Close the whole browser
4.See if data has been submited to server
5.Open the same page again and close ONLY the tab this time
6.See if data has been submited to server
7.Data will NOT be sent to server.


Expected Results:  
Data should be always sent to server on page exit
