UISplitViewController loses detail navigationItem

1. Create a brand-new project using the "Master Detail" template

2. Edit the detail controller to add something - anything - to the navigationItem, e.g. a segmented control or a label to navigationItem.titleView. Or add buttons. Doesn't matter.

3. Run the project on an iPad

4. Bring in another app using the multitasking gestures; dock the app on the side (left or right).

5. Slide the divider to change the size of the two apps. Make the UISVC collapse; then make it expand.

6. Notice when expanding, the navigationItem from the Detail controller is gone. Poof!


The expection is that the navigation bar and its items remains constant.
