Description:

With 2 different TextInputs (default and keyboardType="number-pad") wrapped in KeyboardAvoidingView with behavior set to "height" and a single button on the bottom of the screen, keyboard avoiding is not behaving correctly.
Opening first TextInput (default) results in proper showing button placed on the bottom, but as soon as we switch to second TextInput (set to "number-pad") screen is not scaled properly and button hides behind a keyboard.

Steps To Reproduce

1. Initialize a new RN project
2. Copy/paste code from snack: https://snack.expo.io/@devstarman/keyboardavoidingview-textinput-bug
3. Run the app using react-native run-android
4. Click at first TextInput (with placeholder "enter text")
5. Click at second TextInput (with placeholder "enter number")
6. Observe how the "next" button disappears.

Expected Results

It's expected to scale properly no matter what type of keyboard is used in TextInput.
Changing behavior to "padding" solves issue BUT then there is another issue already reported in Dec 2019: #27526
