iOS 14 TextInput jumping and auto-scrolling on tap (React Native) - how to disable?

New RN build from scratch. Only the code below exists.

Xcode version 12.0.1 iOS 14 RN 0.63.3

Scrolling and tapping makes TextInput jump to random places.

export default class TextField extends Component {

   constructor(){
     super();
     this.state={textInput: ''}
   }

  handleChangeText = (textInput) => {
    this.setState({ textInput });
  }

    return (
        <View style={{flex: 1, backgroundColor: 'blue'}}>
           <TextInput 
            style={{marginTop: 100, height: 300, backgroundColor: 'white'}}
            value={this.state.textInput}
            multiline={true}
            onChangeText={this.handleChangeText}
          ></TextInput>     
        </View>
    )
}

How can this be disabled? Or fixed so that the autoscroll goes to the correct place?
