Description

[Stephen W. Cote]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; rv:1.7.3) Gecko/20040913 Firefox/0.10.1
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; rv:1.7.3) Gecko/20040913 Firefox/0.10.1

On the example page
http://www.whitefrost.com/reference/2004/10/06/window_test.html the
onbeforeunload event is set to invoke a function that will open a new window. 
Clicking the example link, entering a new URL, or closing the window if it was
opened in a tab will result in a new window being opened to www.mozilla.org

Reproducible: Always
Steps to Reproduce:
1. create an event handler for window.onbeforeunload
2. in the event handler, open a new window
3. navigate away from the example page, or closing the tab (at least one tab
must be open)

Actual Results:  
The window opens.

Expected Results:  
Blocked the window.
