Suggested change
if(searchExpandedKeys&&loadData&&!treeDefaultExpandAll){
returnexpandedKeys||[];
}
returnexpandedKeys;
returnexpandedKeys||[];

这里和直接这样有啥区别？

这里主要差异在 treeDefaultExpandAll 场景。
初始化时如果没有传 treeDefaultExpandedKeys，expandedKeys 是 undefined。直接 return expandedKeys || [] 会返回 []，下游 Tree 收到 expandedKeys={[]} 后会进入受控展开状态，defaultExpandAll 就不会生效，所以默认展开会失效。
