When I was using the plugin “boxreorderer”, I found a serious animation problem with drag and drop ordering. As the drag component moved to the right, the other components kept moving back and forth left and right, stopping automatically for an unknown amount of time. So I looked at the official case and found that there was also this problem, so I recorded the screen for this.

I tried version 7.5.1 is normal, but in version 7.6 and above have this problem.

Ext.create('Ext.toolbar.Toolbar', {
    height: headHeight,
    border: 0,
    overflowHandler: 'menu',
    items: headItems,
    plugins: [{
        ptype: 'boxreorderer',
    }],
});
