Steps to reproduce

What is expected?

预期是 person.name发生改变，person.family.husband.name不改变；

What is actually happening?

当我使用change函数，同时改变一个通过shallowReactive定义的对象的浅层和深层的时候，深层对象也会发生改变。

Vue always updates the whole component when a reactive change happens.

• the update is cause by the reactive change of person.name.
• During the update, the changed value for person.family.husband.name is used in the template update.

当发生响应式更改时，Vue 总是更新整个组件。

• 更新是由 person.name 的被动更改引起的。
• 在更新期间，person.family.husband.name 的更改值用于模板更新。
