Month picker issue in combination with "prevent-min-max-navigation" and max and min date

[NicoHof]

Describe the bug

This may be two different bugs but can be both seen in the repro example

• Arrow back is not disabled. It should be since I cannot select something from 2022
• I cannot select "May 2023". The entry is not in "disabled state" - User can click it but not "select" it

Steps to reproduce the behavior:

https://codesandbox.io/p/sandbox/vue3-datepicker-monthpicker-issue-forked-s8dy7v?file=%2Fsrc%2FApp.vue

1. Open picker
2. Use "Year back button" - Can come to year 2022. But should not be, right?
3. Try to click (works) and then select (does not work) "May 2023"

Expected behavior

• No back button enabled
• Can select May OR disable May in calendar (prefer selectable, since minDate is 20. May 2023, so May 2023 should be selectable)

Hint The not disabled arrow button also happens if you change the start year in this example to 2024. Then you can go to 2025! (2022 disabled then though)

Desktop & mobile (please complete the following information):

• Library version: 8.5.0

Looks like the issue is only present if v-model is provided

@Jasenkoo I tried version 8.6.0 with your fix for the disabled navigation buttons. Works fine!

But I noticed, that the selection of a month at the beginning of the period is still an issue.

• "May 2023" is available to select. I can click on it. But I cannot "submit" it in the end.
• IMO this behaviour is strange and missleading for the user. If its not selectable (Button click) it should also be disabled for clicking, right?
• But even better would be: It can be selected. In this example: since minDate is 20. May. 2023, so May 2023 should be selectable as its inside of the "min date limitation"?
