Thanks for taking care.

I referred the configuration from chrome branch. I assume that good 
amount of testing has already been done on this configuration.
I manually check all configuration and run chrome on this change which 
works properly. Did not see any abnormal behavior.
So if something missed then it is just human error which did not catch 
on 2 level of self review.

Again  any change on this configuration can be expected based on new 
testing or bringung new modules.
