taro 3.0.8 "taro-ui": "^3.0.0-alpha.3" 微信小程序 AtIndexes 组件点击索引列表有时无法跳转到指定索引

跟官方代码一模一样

import Taro from '@tarojs/taro'
import { View } from '@tarojs/components'
import { AtIndexes, AtSearchBar } from 'taro-ui'
import mockData, { CityItem } from './mock-data'
import './index.scss'

interface IndexesState {
value: string
}

export default class Index extends Taro.Component<{}, IndexesState> {
public config: Taro.PageConfig = {
navigationBarTitleText: 'Taro UI'
}

public constructor () {
super(...arguments)
this.state = {
value: ''
}
}

public componentDidMount (): void {
console.log(this.scrollIntoView)
// this.scrollIntoView && this.scrollIntoView('top', 0)
}

private scrollIntoView (key: string): void {
console.log('不需要实际实现', key)
}

private onClick (item: CityItem): void {
console.log(item)
}

private handleActionClick (): void {
if (!this.state.value) {
return
}
this.setState({
value: ''
})
this.scrollIntoView && this.scrollIntoView(this.state.value.toUpperCase())
}

private handleChange (value: string): void {
this.setState({
value
})
}

public render (): JSX.Element {
return (

{/* 基础用法 */}

{ this.scrollIntoView = fn }}
