vue 拖放控件設(shè)置數(shù)據(jù)更新了，視圖也更新了，點(diǎn)擊非激活元素?cái)?shù)據(jù)被重置，為什么呢？

項(xiàng)目中使用vue-draggable-resizable這個插件，項(xiàng)目地址https://github.com/mauricius/...
數(shù)據(jù)結(jié)構(gòu)如下：

    id: '001',

現(xiàn)在發(fā)現(xiàn)一個問題，就是當(dāng)我點(diǎn)擊其中一個元素時激活拖動的元素，然后進(jìn)行resize操作，此時通過vue瀏覽器插件查看，元素大小數(shù)據(jù)已被更新，視圖也更新，但當(dāng)我點(diǎn)另外的元素后，原來第一次點(diǎn)擊的元素寬高數(shù)據(jù)被重置為初始值了，什么鬼？這個是插件問題，還是我vue數(shù)據(jù)循環(huán)問題呢？ 有沒有大神指導(dǎo)一下，謝謝。
