富文本导致FairyBatching数组越界报错的问题

我制作了一个包含富文本的界面，且富文本的自动大小方式为自动收缩，在打开该界面时同时启动了FairyBatching，报错数组越界。具体定位到在报错方法中遍历Children时，是提前取出Children的count作为循环条件，但在循环体内的child.GetBounds()方法中，会走到RichTextField的EnsureSizeCorrect()方法，该方法里的Cleanup()方法会导致父级的Children数量减少，但由于对Children的遍历是提前取出了数量作为循环条件，因此循环任然在继续，但Children已经没有了。
报错信息如下：
