[LayaAir 1.0]使用对象池重复使用skeleton报错，请问有解决方案吗？谢谢

引擎版本：1.7.19

描述：
使用对象池重复使用skeleton报错，但每次new Laya.Skeleton() 就没问题。
 
伪代码：
const ​temp = new Laya.Templet();
temp.parseData(xxx, xxx, 0);
 
// 从对象池中获取skeleton
const skeleton = Laya.Pool.getItemByClass('abc', Laya.Skeleton);
skeleton.init(temp, 0);
 
// skeleton使用完放入对象池
Laya.Pool.recover('abc', skeleton);

    问题描述:
    我在你们官网的引擎示例里的骨骼动画--多纹理，执行下面的测试代码，测试代码是改的示例代码，第一次点击屏幕播放没问题，播放完后Skeleton放入对象池， 第二次点击屏幕使用对象池里的Skeleton播放，就报错了，是不是你们引擎的对象池不支持Skeleton或者是我的使用姿势不对？麻烦看看，谢谢。

    首次将对象拿出来使用之后可能对对象做了某些操作 在放回对象池之前需要将这些操作还原回去 即有可能是有脏数据影响到了你的重复使用
