安卓微信版本更新8.0.27后，小程序canvas  bindtouchstart、bindtouchmove事件失效？？？？

<canvas id="tipsMoveTouc" type="2d" class="tipsMoveTouc" disable-scroll="{{false}}" bindtouchstart="bindtouchstart" bindtouchmove="bindtouchmove" bindtouchend="bindtouchend" bindtap="bindtap" bindlongpress="bindlongpress"></canvas> bindtouchstart: function (e) { // 检测手指点击事件 console.log('bindtouchstart'); }, canvas 2d 无法触发事件，请问是什么原因啊，安卓 Redmi K30
