Enable inline vertical scroll

[cwist2]

On mobile, it would be great to have a vertical scrolling calendar, similar to the Calendar app on iOS/Android. I want to add months as I scroll down to the bottom. I've tried many approaches to get this to work, but I consistently encounter issues when dynamically changing the count of MultiCalendarsOptions.

Here is a sample of the current behavior:
https://stackblitz.com/edit/vuepic-vue-datepicker-nqzywp?file=src%2Fcomponents%2FPlayground.vue,src%2FApp.vue

As you can see on the Stackblitz, each added month is displayed as "January 0".

Describe the solution you'd like
The solution would be to allow changing the count of MultiCalendarsOptions.

Describe alternatives you've considered
I found that calling datepickerRef.value.setMonthYear({}) (where datepickerRef is the ref of the Datepicker component) after incrementing the count of MultiCalendarsOptions works, but only if the modelValue of the Datepicker component is not defined.

Tested on vue-datepicker v8.7.0

+1 for this feature, it would be great, encountered the same issue recently, it is quite blocking our development as we really wanna use this lib.
