鸿蒙系统中的微信小程序组件canvas bindtouchstart等触摸事件无效的问题？
<view class="handWriting" @tap="log(1)"> <canvas class="handWriting-canvas" disable-scroll="true" bindtouchstart="uploadScaleStart" bindtouchmove="uploadScaleMove" bindtouchend="uploadScaleEnd" canvas-id="handWriting" @tap="log(2)"> </canvas> </view> 鸿蒙系统里 画布点击事件log皆有打印，划屏事件则全无打印，父级和子集高宽都有设置，苹果和安卓正常，鸿蒙则划屏无法促发方法
