Is this a bug report?

Yes

Have you read the Contributing Guidelines?

Yes

Environment

1. react-native -v: 0.48.3
2. node -v: v6.9.4
3. npm -v: 3.10.10

Then, specify:

• Target Platform: iOS

• Development Operating System: macOS

• Build tools: Xcode

Steps to Reproduce

1. Focus on TextInput (keyboard appears)
2. Double tap home button and quickly switch to other app (e.g. Messages)
3. Toggle keyboard in other app
4. Again double tap home button, while in app-switch view, keyboard is missing in React Native app, leaving padding from KeyboardAvoidingView still there, making it look bad.
5. Doesn't always happen, sometimes you need to try few times

Expected Behavior

Keyboard will stay visible while app is in app-switch view, or KeyboardAvoidingView will adjust it's padding back to normal, like when keyboard is not visible.

Actual Behavior

Keyboard disappears in app-switch view.

Reproducible Demo

Note: Test on device or xcode simulator preferably, it's a bit tricky to go to app-switch view in simulator on Snack website.

It might not always work when following reproduction steps, but please try few times. If keyboard is visible in React Native app, please try to switch to different app and close keyboard as quickly as possible, so app is still in background state.
