Open Radar

 
Summary:
In order to present a new view controller in an overlay style in the iPhone while keeping the underlying one visible I set the modal presentation style of my view controller hierarchy to UIModalPresentationCurrentContext. 
This achieves the desired effect but whenever I use a unwind segue to dismiss that modal view controller I have to explicitly dismiss it but only if the origin view controller is embedded in a UINavigationController. This differs from all the other modal presentation styles where just triggering an unwind segue brings me back to the right view controller.

Steps to Reproduce:
Open the sample project and touch the "Launch Modal" button;
Verify that you can see through the modal view controller;
Touch the "Dismiss this screen" to go back to the origin view controller.

Expected Results:
After performing the previous steps the modal view controller should have been dismissed.

Actual Results:
The modal view controller is not dismissed and the developer has to dismiss it explicitly in the unwind method.

Version:
iOS 7.1 (iOS 8 does not let me see through)

Notes:


Configuration:
All devices including the simulator
