Javascript 聚合元素中的React.js组件：每个鼠标/滚轮/按键事件都有错误

聚合物0.1.1和React.js 0.8.0

减少了案例：在每个鼠标/滚轮/按键事件中都会出现如下错误：

"TypeError: Cannot set property target of #<v> which has only a getter

    events.js:328

“TypeError:无法设置#的属性目标，它只有一个getter
在b(http://cdnjs.cloudflare.com/ajax/libs/react/0.8.0/react.js:7794:28)

在HTMLDocument.o(http://cdnjs.cloudflare.com/ajax/libs/polymer/0.1.1/platform.js:29:25217)" 
events.js:328

看起来Polymer的events.js与React的合成事件发生冲突

错误堆栈到此结束（react.js:7794）：

---

//TODO:Remove when synthetic events ready，这是针对IE的这还没有在React发行版中，但该代码在两个月前被删除：


如果您在当前主机上构建了React off的副本（
npm install；grunt build
），您将不会再看到错误

  // TODO: Remove when synthetic events are ready, this is for IE<9.
  if (nativeEvent.srcElement &&
      nativeEvent.srcElement !== nativeEvent.target) {
    nativeEvent.target = nativeEvent.srcElement;
  }
