【问题描述】：
我正在加载一个非常标准的地图，例如：
map = new Microsoft.Maps.Map(document.getElementById('map_canvas'));
在 Chrome 中它工作正常，但在 IE11 中，我在地图代码中遇到异常：
0x800a01b6 - JavaScript 运行时错误：对象不支持属性或方法“matchMedia”
Bing 地图代码中的行是：
return window.matchMedia("(-ms-high-contrast:active)").matches
window 变量已定义，但如果我检查它 matchMedia 未定义。
整个堆栈跟踪是：
