问题描述：
窗口中代码如下：
<a href="#" class="easyui-linkbutton" data-options="iconCls:'icon-search'" >Search</a>
当窗口有滚动条时，按钮本身随滚动条滚动，而图标和文本“search”不随之滚动，但当你把单击下图标，图标迅速滑落到按钮本身的位置，请问是什么原因，是慢的原因么？
linkbutton不会随窗口滚动的，你自己加的代码？
你看下官网的示例Basic LinkButton
看看在你的浏览器上会不会也是同样的情况，如果是，那么可能是浏览器的问题。如果正常的，那是不是你的按钮还有其他的样式或者代码控制。
贴一下测试代码吧，运行时候，调整窗口，观察west区域的变化：
