Zooming feature is broken. Can't zoom the page with zooming keys. As well as that, it populates artifacts shown on page.

Reproducible: Always

Steps to Reproduce:
1. Open Fennec 
2. Navigate to http://www.google.com
3. Use CTRL+DOWN shortcut (hold it for a while)
Actual Results:  
Page is not zooming out (or it zooms out only a little). 

As well as zooming out, zooming in doesn't work well too (but a little bit better).

Additionally when I rotate device into portrait mode I see various artifacts. It seems like multiplied page content at various zoom levels placed one on another. It sometimes gets updated properly after a short while, but sometimes not. Looks horrible.

Expected Results:  
Page should be properly zoomed out and it's zoom status should be updated. No artifacts after that should be visible.

This is due to tile caching which will be removed once layers lands. I'm not sure of the bug id though.
