问题
不停的拖动tab栏，会不断更新布局。
Dragging the tab bar continuously will update the layout constantly.
解决办法
进入 ExtJS 包，打开ux目录下的BoxReorderer.js文件，找到337行的位置，包裹上Ext.defer即可。
Enter the ExtJS package and open the BoxReorderer.js file in the ux directory. Wrap the code at line 337 with Ext.defer to delay its execution.
Like this：
// Make the Box Container the topmost layout participant during the layout.
Ext.defer(()=>{
container.updateLayout({
isRoot: true
});
},300);
