Description
I'm using an InputAccessoryView to create a sticky TextInput. When using a growing multiline TextInput, the TextInput's height increases and grown down behind the keyboard.

Xcode: Xcode 9.3 Build version 9E145
Android Studio: 3.0 AI-171.4443003

react: 16.3.1 => 16.3.1
react-native: 0.55.2 => 0.55.2

Research direction
The issue identifies InputAccessoryView and a multiline TextInput but names no source file or test. Start by reproducing the growth-behind-keyboard behavior on iOS, then trace the InputAccessoryView layout path. Done means the accessory view remains flush with the keyboard top as the TextInput grows.
