When you close the "View Source" page on certain websites, the entire fxmetro browser stalls for a good 10 seconds or so. During this time, you cannot open tabs, go back etc.. the browser is completely unusable.

Video of the issue:
- http://youtu.be/sypnUjy4QZA

Steps to reproduce the issue:

1) Open fxmetro
2) Once opened, type in Wikipedia into the URL text field and than select the "Wikipedia" search icon
3) Once the website has been loaded, slide in the Navigation App Bar and tap on "Settings -> View page source"
4) A new tab will be created (should notice some jank)
5) Once the view-source tab loads, close it by taping the "X" under the Tab App Bar. You'll instantly see fxmetro stalling

Current Behavior:

- The entire fxmetro stalls for several seconds while closing particular view-source tabs

Expected Behavior:

- The view-source tab should close smoothly without jank or stalls. Should be a smooth experience
