Html page with meta tag for repeating bug

When I add meta tag 
    <meta name="viewport" content="width=device-width, user-scalable=no" />
to my site, and user on touch screen device pull scroll down to pull content out of top border he can scale the site despite the meta tag.
In this case functionality of this meta tag does not working.

How to repeat this bug:
1. On touch screen device open attached html
2. Pull the scroll down
3. When content pulled try to scale(by two touches)
