[Bug Report][3.4.0] Problem displaying <v-date-picker>, it does not appear by default on the allowed dates

[alanscordoba]

Environment

Vuetify Version: 3.4.0
Vue Version: 3.3.8
Browsers: Chrome 119.0.0.0
OS: Windows 10, Windows

Steps to reproduce

Just view the sample example

Expected Behavior

In the example it appears in the month of November.

Actual Behavior

I hope it appears in December, since there are no dates available in November, and also the date initially selected is also in that month.

The problem seems to be with the date format you passed. It is invalid. It works when i pass the valid date like below -

Invalid - const datePicker = ref(new Date('2023/12/10T00:00:00-03:00'))
Valid - const datePicker = ref(new Date('2023-12-10T00:00:00-03:00'))

Here is the working example

Thanks for your response, but in my environment it doesn't work, since the data comes from an API. I'll try to explain it:

datePicker is initialized as const datePicker = ref()

Then, the data coming from the API is loaded. At that time when is initialized to the current month instead of the selected month based on the v-model date.

Here is an example of how to do it:

Sorry to insist on this topic, but I think it is a bug, the component is not displayed correctly. I pass the link to play it, if you press the button you will see that the calendar appears, it is not displayed in the month of December, as expected, thank you:

Demonstration

I clarify that it is also happening in version 3.4.1

This problem had been resolved in 3.4.3, but reappeared in 3.4.8 and is maintained in subsequent versions.
