Inspecting the inspector I see: [Error] TypeError: null is not an object (evaluating 'document.body.classList') _windowFocused (Main.js, line 783) (anonymous function) ([native code], line 0) Weird.

Well we do add the _windowFocused listener before the DOMContentLoaded event. So if it fires early it will cause this. I guess we should delay adding the listener until DOMContentLoaded.
