Summary:
Using the new iOS8 UIPopoverPresentationController approach to presenting popovers, I experienced a situation (easy to repeat in my codebase) where tapping once in the dimming region to dismiss the popover works, but performing a double tap not only dismissed the popover, it triggered a dismissal on the parent view controller defining the presentation context.

In my situation, I have a container view controller that comes on screen in stock modal fashion. It is a container for several child view controllers, one of which uses the UIPopoverPresentationController approach to present a popover.

The child view controller that requests the presentation of the view controller configured for UIModalPresentationPopover style never received a dismissViewControllerAnimated:completion: call, but its parent view controller (show in the debug screenshot attached) does.

It seems like without a UIPopoverPresentationControllerDelegate defined that implements the delegate method 'popoverPresentationControllerShouldDismissPopover:', your internal/private method 'dimmingViewWasTapped:' is jumping to the presentation context controller and invoking 'dismissViewControllerAnimated:completion:' on it.

Steps to Reproduce:
See code snippet example here: http://stackoverflow.com/a/26085641/535054, used in conjunction with the view controller hierarchy described in the Description section above.

Expected Results:
I expected the popover to dismiss, but no other side effects, from a double tap on the dimming view setup by the popover's presentation.

Actual Results:
The popover is dismissed, and the presenting view controller is also dismissed!

Version:
 Xcode 6.0.1 (6A317), iOS8
