76568 - [xpcdom] setting childWindow.opener = self; forces JS variables not to increment its value.

Status: VERIFIED FIXED

(Core :: DOM: Core & HTML, defect)

Description

[Prashant Desale]

Sounds little confusing ?
Well testcase will be self explanatory.

If we try to set childWindow.opener = self; & if we are incrementing some other 
JS variable value, its not getting incremented. 
This blocks automation testing process.

BUILDS: XPCDOM

STEPS TO REPRODUCE:
1] Please download zip file I'm going to attach. [Two testcases]
2] Extract both in same directory.
3] file 'ggg2.html' is main file. open this file using xpcdom builds.
4] click button "Open new win".
5] you will see infinite alerts with JS variable "tcnum = 0". [Kill this proces 
somehow. "holding Return-key on keyboard & Clicking window exit icon at same 
time"]
6] Now open the source code of "ggg2.html" & comment line 
"testWin.opener = self;"
7] Now try again steps 3 & 4.
8] Now you will see 4 alerts with JS variable "tcnum" incrmenting its value on 
every alert by 1. [This is what is supposed to happen.].

EXPECTED RESULTS: You should see 4 alerts in entire process showing 'tcnum = 0',
'tcnum = 1', 'tcnum = 2', 'tcnum = 3'

ACTUAL RESULTS: You see infinite alerts showing 'tcnum = 0', ..............[you 
have to kill the process somehow]


THIS IS AUTOMATION BLOCKER.

I said I will be attaching zip file.
Instead I attached two HTML files "Two files for one complete testcase".
"ggg2.html" is main file & "ggg3.html" is child window file.
