测试手机：小米5
现象：手机页面加载地图，双手操作放大，APP卡死，APP卡住后，点击物理返回键是能返回的，但页面全部不能点击。
页面代码：
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<meta name="viewport" content="initial-scale=1.0, user-scalable=no" />
<link rel="stylesheet" href="css/mui.min.css">
<title></title>
</head>
<body>
<div class="mui-content mui-scroll-wrapper">
<div id="allmap" class="mui-scroll" style="width: 100%;height: 500px;"></div>
</div>
</body>
<script type="text/javascript" src="http://map.qq.com/api/js?v=2.exp" ></script>
</html>
<script type="text/javascript">
initMap() ;
function initMap()
{
var longitude = 106.550337 ;
var latitude = 29.494741 ;
window.map = new qq.maps.Map(document.getElementById("allmap"), {
center: new qq.maps.LatLng(latitude,longitude),
zoom:14
});
} </script>

Ignored attempt to cancel a touchcancel event with cancelable=false, for example because scrolling is in progress and cannot be interrupted.
各位，帮忙看看怎么解决？谢谢！
发现用Hello H5+这个例子APP里的Map页面，放大太快的时候，也会卡住，不知道什么原因了
