当按钮组属于溢出中的组件时，溢出按钮不起作用两次

Question

在论坛中查找类似的问题。

Overflow button does not work twice when a button group is among the components in the overflow.

这是固定的吗？

我的工具栏代码片段如下所示：

           {
                id: 'mypanel',
                xtype: 'panel',
                autoScroll: true,
                region: 'center',

                dockedItems:[{
                    xtype: 'toolbar',
                    dock: 'top',
                    enableOverflow: true,
