Tested and fixed on iOS.

How to reproduce:

• Create a scene with input field(s)
• Swipe down from above or go to the home screen to trigger a application state change
• Go back
• Input fields are not accessible anymore content is blanked out.

Not sure what purpose they serve. I see little value in managing their accessibility on app state changes since you won't be able to access them anyway at that point. That's why I got rid of them.
