button 的submit事件失效

- 预期表现

点击button应该正常触发submit事件

- 复现路径

两个连续的textarea，先输入下方的textarea，然后输入上方的textarea，ANDROID手机submit事件100%失效

- 提供一个最简复现 Demo

<view class="page__hd">

<view class="page__bd">

<form bindsubmit="formSubmit">

<view class="weui-cells__title">售楼地址</view>

<view class="weui-cells weui-cells_after-title">
