想实现一个简单的图片裁剪功能，但是图片onTouchStart没有被调用，但是下面的view是又被调用的。是因为image标签无法使用onTouch的事件监控吗

import Taro  from '@tarojs/taro';
import React, { useEffect, useImperativeHandle } from 'react';
import { View, Canvas, Image } from '@tarojs/components';
import "./index.scss";

interface ImageCropperPropsType {
	imgSrc,
	cut_ratio?: 1, //裁剪框的 宽/高 比
}
const ImageCropper: React.FC <ImageCropperPropsType> = props => {

	const { imgSrc, cut_ratio } = props

	useEffect(() => {

	})

	const handleTouch = (e) =>{
		console.log('e', e);
	}
	const handleClick = (e) => {
		console.log('click', e);
	}

	return (
		<View
			className='cut_wrapper'
			>
		<Image
			className='img'
			src={imgSrc}
			onTouchStart={handleTouch.bind(this)}
			/>
			<View onTouchStart={handleTouch.bind(this)}>
				ghhgdf
			</View>
		</View>
	)
}

export default ImageCropper;

 const string = '## header'
 <View className='course-anlist-item-content' dangerouslySetInnerHTML={{__html: string}} />

渲染失败

通过<RichText>渲染出来的效果存在很多修饰语，有什么方法可以解决
