@alilc/lowcode-plugin-schema 在重复import相同的schema的时候会导致X6里面的边消失。

我在import一个schema的时候，当我两次import的内容是一样的时候，就会导致边消失。
我所使用的时候lowcode engine 和 antv x6结合的方式来实现的，这个是哪里出了问题呢？

Start by reproducing the issue with lowcode engine and AntV X6 by importing the same schema twice, then compare the schema and edge state before and after the second import. Done means repeated imports preserve all X6 edges instead of making them disappear.
