[Full-disclosure] Bypassing Google Chrome 4 Javascript Filter

Bypassing Google Chrome 4 Javascript Filter
===========================================

Google Chrome 4 included a new Javascript Filter which allows users to disallow 
javascript in websites. This filter doesn´t allow to web sites to execute any 
Javascript code if the web site is accessed directly.
This protection, can be easily bypassed since it only is applied when the web 
site is accessed as the main page. This means, if the blocked domain site is 
used in an iframe object, then the Javascript filter doesn´t block any 
Javascript code.
