重现步骤

###选择省份后，观察市是否动态加载

期望的结果是什么？

选择对应的省后加载省下方对应的市，选择市后动态加载区

实际的结果是什么？

选择省后市无法动态加载，并且出现空值的现象

这个问题我也遇到了之前版本4.1.6没问题，升级到了4.2.0也出现了这个bug。@change的回掉参数只返回了一个{
"custom": "province"
}.。next和value没有返回，这个bug很严重

这个问题虽然解决了，但是不完美。
在选择省的时候，市和区的数组需要一个初始值，给个空数组会选择了省控件就关闭了。
需要这样写：
const address = reactive({
placeholder: placeholder,
province: [{}],
city: [{}],
country: [{}],
town: []
});
