Summary:
When a landscape only UIViewController is created and set as the root view controller of a UIWindow, the view controller is incorrectly displayed/sized (as if it was in portrait). This does not occur in iOS 7.

Our specific use case for this is the Heyzap Advertising SDK. When displaying a fullscreen video ad, we create a new window and set a landscape only UIViewController as its rootViewController, then call `makeKeyAndVisible` on the window to display the ad. 

Several people are experiencing the same problem, though they're not second window at runtime, but rather having this problem with a landscape only root view controller:

One dev from there says he filed a bug #17960800 about this.

Steps to Reproduce:
(See the attached sample project zip file; it already has this implemented with helpful NSLog statements)

1. Create a new Xcode project (I used Xcode6-Beta6)
2. Create a LandscapeOnlyViewController class with these methods implemented:

- (void)viewDidLoad {
    [super viewDidLoad];
    self.view.backgroundColor = [UIColor greenColor];
    
}

- (NSUInteger)supportedInterfaceOrientations {
    return UIInterfaceOrientationMaskLandscapeRight;
}

3. In the App Delegate, create a new window after the app launches, making sure to hold a strong reference to it:

@property (nonatomic, strong) UIWindow *secondWindow;

dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(2 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
        self.secondWindow = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds];
        LandscapeOnlyViewController *vc = [[LandscapeOnlyViewController alloc] init];
        self.secondWindow.rootViewController = vc;
        [self.secondWindow makeKeyAndVisible];
    });

4. Run the app

Expected Results:
The LandscapeOnlyViewController's view covers the screen in a landscape orientation.

Actual Results:
The view looks to still be in portrait, despite the device being in landscape
