Summary:
Modal transitions between view controllers with different status bars should animate the status bar style and visibility in tandem with the transition.

Steps to Reproduce:
1) Launch the provided sample app.
2) Tap on the Open button
3) Note that the presented VC has a white status bar
4) start closing the presented VC by a closing pinch gesture

Expected Results:
- The white status bar text should gradually cross-fade to black text
- This cross-fade should be coupled with the percent of the percent driven transition

Actual Results:
- The text color changes to black right after the interactive transition was started
- The text color jumps to white if the interactive transition is cancelled

Version:
iOS 8.3 (12F5037c)

Notes:
The same problem exists if the presented VC has a hidden status bar. In that case I would expect the status bar to fade out during presentation and fade in gradually according to the percentage during interactive dismissal.

Configuration:
iPhone Simulator
