What is expected?
首次设置v-model绑定的值的时候，不要触发on-change事件

当设置Select组件为多选的时候，给v-model绑定的变量设置一个初始值时，on-change事件触发了

What is expected?
Do not trigger on-change events when setting the value of the V-model binding for the first time.
What is actually happening?
The on-change event triggers when the Select component is set to be multi-select and an initial value is set for the variable bound to the V-model

这个地方应该始终不等吧，虽然数组的值是相等的，但不是同一个数组，所以总会触发on-change事件
