web页面随着setComposition次数增多，存在内存增长不会消减 。在ios端播放两次中途会有报错，偶尔还会crash。

我们业务场景是一次完整抽卡动画由11个pag顺序切换播放。用户抽卡一次播放一次。这里使用一个pagView用setComposition切换pagFile实现的。

有以下问题

1. web页面随着setComposition次数增多，存在内存增长不会消减
   2.在ios端播放两次中途会有报错，偶尔还会crash。报错内容如下

这里在官方demo上改了set-composition.html复现以上问题

1、在mac浏览器运行，点击多次看内存有增加  2、在ios端点击多次直到卡顿，看vconsole有报错
