Summary:
If you have an app with a modal interface controller visible, and you background the app, go to the clock face and reopen it, it will hang (no touch or scroll events), and will eventually either crash or dismiss the modal interface controller
Steps to Reproduce:
1. Launch sample app.
(Make sure to set a modular clock face with a modular large complication)
2. Present modal
3. Press the crown to go to the home screen.
4. Press the crown to go to modular clock face
5. Press the complication so the app opens
Expected Results:
The app is fully functional
Actual Results:
Can't scroll or tap.
Force touch seems to do something.
The app will eventually crash with this log
