Styles disappear after sdk36/ react-navigation v5 update

Steps to Reproduce

I've migrated an existing sdk35/react-nativation 4 to sdk36/react-navigation 5, I have a strange thing: all my styles done with react-native-extended-stylesheet aren't recognized : in styles.js, I have just an

export default EStyleSheet.create({ container: { flex: 1 }, ... }),

and used as

import styles from './styles', ... render() ... <KeyboardAvoidingView style={styles.container}

If I replace by style={{flex: 1}}, I recover the expected style ...

When I check styles in render, it is empty {} ! styles.js is well loaded (I've put a console.log to check)

This is similar to #100
