HarmonyOS 鸿蒙Next WebView在页面在路由中第三层时，页面数据就会被清空

JumpPage 的网页回到了一开始的网页。 对照iOS: JumpPage 的网页保持在之前点中的链接。 最小demo:

import { AppRegistry } from 'react-native';

import App from './Root2';

AppRegistry.registerComponent('appName', () => App);

import React, { useEffect } from 'react';
import { NavigationContainer } from '[@react-navigation](/user/react-navigation)/native';
import { createStackNavigator } from '[@react-navigation](/user/react-navigation)/stack';
import JumpPage from './JumpPage'
import JumpPage2 from './JumpPage2';
import JumpPage3 from './JumpPage3';

const Stack = createStackNavigator();
const Root = () => {
 return <NavigationContainer> < Stack.Navigator
 initialRouteName = { 'JumpPage' }
 screenOptions = { { headerShown: false, }
} > < Stack.Screen
key = { 'JumpPage' }
name = { 'JumpPage' }
component = { JumpPage }
/> <Stack.Screen key={'JumpPage2'} name={'JumpPage2'} component={JumpPage2} / > < Stack.Screen
key = { 'JumpPage3' }
name = { 'JumpPage3' }
component = { JumpPage3 }
/> </
Stack.Navigator > < / NavigationContainer >
}

export default Root
