无法使用ExtDnd5对节点进行排序，只能设置为子级

Ext.create('Ext.tree.Panel', {
    renderTo: Ext.getBody(),
    width: 400,
    height: 300,
    title: 'Sortable Tree',
    store: Ext.create('Ext.data.TreeStore', {
        root: {
            expanded: true,
            children: [
                { text: 'Node 1' },
                { text: 'Node 2' },
                { text: 'Node 3' },
                { text: 'Node 4' },
                { text: 'Node 5' },
            ]
        }
    }),
    viewConfig: {
        plugins: {
            ptype: 'treeviewdragdrop',
            enableDrag: true,
            enableDrop: true,
            appendOnly: true
        }
    },
    listeners: {
        drop: function (node, data, overModel, dropPosition, eOpts) {
            console.log('Node dropped:', data.records[0].get('text'));
            console.log('New parent:', overModel.get('text'));
        }
    }
});
