ExtJs 6.2.0 求助 如何给Ext.Label 加滚动条

代码如下:
Ext.define('myApp.view.myInfo', {
extend: 'Ext.Toolbar',
alias: 'widget.myinfo',

requires: [
'Ext.Label'
],

items: [
{
xtype: 'label',
bind: {
html: '{info}'
},
itemId: 'id_lblInfo',
style: {
textAlign: 'left'
},
width: '100%',
left: '1%',
margin: '10px',
scrollable: {
direction: 'horizontal',
directionLock: true
}
}
]
});

上面代码运行时报错: Uncaught NoModificationAllowedError: Failed to execute 'insertAdjacentHTML' on 'Element': The element has no parent. 给Label加Scrollable属性有什么问题吗? 哪位大侠知道, 求教
