Summary:
The UIPopoverPresentationController automatically resizes to a wrong size after a UIAlertController (action sheet style) is shown by the presented view controller.

Steps to Reproduce:
1. Create a new event in Calendar.app on iPad
2. Select the event to see the details in a popover
3. Select Edit to edit the event
4. Select Delete Event and the Cancel

Expected Results:
The alert controller should be dismissed without resizing the popover.

Actual Results:
The popover is resized to be too small. This happens in any app, which dismisses a UIAlertController inside a UIPopoverPresentationController.
