Describe the bug

I called setProps on Component has an Array type prop. However, the resulting prop value is a concatenation of the new array value and the old array value.

const wrapper = await mountSuspended(Test, {
    props: {
      users: [
        { id: 0, name: 'John' },
        { id: 1, name: 'Kate' },
      ],
    },
  });
expect(wrapper.html()).toContain('John'); // props contain John and Kate
await wrapper.setProps({ users: [{ id: 2, name: 'Bob' }] });
expect(wrapper.html()).not.toContain('John');  // !! props contain Bob, John and Kate

This issue occurs when using Wrapper from mountSuspended, but it does not occur when using @vue/test-utils's mount.

What could be the cause of this behavior?
