@inottn Please help to review. I done and fixed all fail tests .

I don't know if the previous interactions were intentional; if there is an issue, the onChange logic might need to be modified. If I have time, I will see how to adjust it.

I definitely sure that it wasn't intentional. and it is a bug.
I would like do it if you are busy.

[JerryWu1234]

thanks for point out.
now no Area component error, and added edge case.
please help to review it again

I prefer to keep the current behavior. If we reset the option it will break the user experience of date picker or time picker.

ok, if we keep the current behavior.
Is there another workaround to fix it?

How about adding a new prop to enable this new behavior? Such as resetChildren.

I think the default should be false if we add a new prop.

Sorry for the delay. Vant is currently community-driven, and PR reviews might not be prompt, I've been very busy lately, and I apologize again. If needed, you can temporarily resolve issues using methods like pnpm patch.

参考了其他组件库的设计，Picker 支持两种模式：级联模式和非级联模式。在级联模式下，上下级选项存在关联关系，当上级选项变更时，下级会自动重置为第一项，这种设计是合理且用户体验友好的。而 DatePicker 等组件采用的是非级联模式，因此不会受到这种联动逻辑的影响。
