When an iPad's orientation is UIDeviceOrientationLandscapeRight, and the user starts a pan gesture outside the right edge of the screen (i.e., starting a swipe from the camera edge and moving your finger leftwards onto the screen), the expected UIPanGestureRecognizer or UIScreenEdgePanGestureRecognizer (with edge = UIRectEdgeRight) callbacks are never called.

Steps to Reproduce:
1. Create a UIPanGestureRecognizer
2. Attach it to a full-screen view
3. Run
4. Orient the device in landscape, with home button on left and camera on right
5. Start a swipe outside the screen on the camera edge
6. Move your finger to the left onto the screen

Expected Results:
UIPanGestureRecognizer action selector is called, starting when the finger moves onto the screen.

Actual Results:
UIPanGestureRecognizer action selector is never called.

Version:
7.0.6
7.1

Notes:
Sample code:

- (void)viewDidLoad {
    [super viewDidLoad];

    UIPanGestureRecognizer *pan = [[UIPanGestureRecognizer alloc] initWithTarget:self action:@selector(handlePan:)];
    [self.view addGestureRecognizer:pan];
}

- (void)handlePan:(UIPanGestureRecognizer *)pan {
    NSLog(@"panning");
}
