如上代码，属性 CheckedListBoxCollectionProperty 和 CheckedListBoxCollectionProperty2 单独是可以使用的，但是，CheckedListBoxCollectionProperty 里变更时，在 CheckedListBoxCollectionProperty2 属性里也变更成和 CheckedListBoxCollectionProperty 一样了。看起来 CheckedListBoxUITypeEditor 只生成了一个对象，被两个属性共用，希望两个属性单独使用自己的 CheckedListBoxUITypeEditor 对象，需要怎么修改呢？
