Set scrollview scrollEnabled to true, continue to scroll and did not trigger the scroll event

[Micjoyce]

Is this a bug report?

Yes

Environment

Environment:
OS: macOS High Sierra 10.13.1
Node: 8.8.1
Yarn: 1.3.2
npm: 5.4.2
Watchman: 4.7.0
Xcode: Xcode 9.2 Build version 9C40b
Android Studio: 2.3 AI-162.4069837

Packages: (wanted => installed)
react: 16.0.0-alpha.12 => 16.0.0-alpha.12
react-native: 0.48.2 => 0.48.2

Steps to Reproduce

1.View wrapped with a scrollview, scrollview's scrollEnabled prop is false
2.Set scrollEnabled to true when the view layer's onStartShSetSetPanResponderCapture event fires
3.Do not raise your hand to continue sliding down, scrollview's scrollEnabled prop is true but did not trigger a rolling event

Has any idea to fix this.

Reproducible Demo

import React from 'react';
import { StyleSheet, Text, View, ScrollView, PanResponder, Button } from 'react-native';

export default class App extends React.Component {
  constructor() {
    super()
    this.state = {
      enableScrollViewScroll: false
    }
    const data = [];
    for (let i = 0; i < 100; i++) {
      data.push({
        key: i + 'key',
        name: i + 'name'
      })
    }
    this.data = data;
  }
  componentWillMount() {
    this._outPanResponder = PanResponder.create({
      onStartShouldSetPanResponderCapture: (evt) => {
        this.setState({
          enableScrollViewScroll: true
        });
      },
    })
  }
  renderItem = (item) => {
    return (
      <View key={item.key} style={{ height: 40, backgroundColor: '#ccc' }}>
        <Text>{item.name}</Text>
      </View>
    )
  }
  render() {
    return (
      <View
        style={{ flex: 1 }}
        {...this._outPanResponder.panHandlers}
      >
        <View
          style={{ height: 200, backgroundColor: '#eee' }}
        >
          <Text>scrollEnabled: {this.state.enableScrollViewScroll.toString()}</Text>
        </View>
        <ScrollView
          scrollEnabled={this.state.enableScrollViewScroll}
        >
          {this.data.map(item => this.renderItem(item))}
        </ScrollView>
      </View>
    );
  }
}
