Gojs 在 angular 11 中的错误行为

如何解决Gojs 在 angular 11 中的错误行为

我在 angular 11 中使用 gojs 有错误的行为。 如果我使用“Delete key”或“Backspace Key”删除节点，则该节点被删除，但是当我移动另一个节点或在图中执行任何操作时，删除的节点之后添加的节点也会被删除。>

该网站是用 angular 9 生成的，gojs 可以正常工作，一旦我将 angular 更新为 angular 11，除了删除选项之外，一切都可以与 gojs 一起正常工作，它的工作方式与我上面解释的一样。

现在，gojs 在我的开发环境中有这种错误的行为，如果我只将 package.json 更改为角度更新之前的状态，然后删除 node_modules 文件夹并运行“npm i”并再次启动站点，它好好工作。 如果我再次回滚到 angular 11，我会遇到同样的问题。

这里是 angular 11 的 package.json：
