bug: ion-datetime does not scroll to value

[aparajita]

Prerequisites

• I have read the Contributing Guidelines.
• I agree to follow the Code of Conduct.
• I have searched for existing issues that already report this problem, without success.

Ionic Framework Version

v7.x

Current Behavior

According to the ion-datetime docs:

If its value is updated programmatically after a datetime has already been created, the datetime will automatically jump to the new date.

Here's what I'm seeing:

• Create an ion-datetime in calendar presentation mode.
• Scroll to a different month.
• Click to set the value to a date in that month.
• Programmatically set the value to a date in a different month.
• The value changes, but the calendar does not scroll to the target month.

Expected Behavior

The calendar should scroll to the month of the value when it changes.

Steps to Reproduce

1. Open the demo at https://stackblitz.com/edit/8d9oqr?file=src%2Fcomponents%2FExample.vue.
2. Scroll to any month other than November 2023.
3. Click on a date in that month. The value changes accordingly.
4. Click "Reset". The value is changed to 2023-11-17T00:00:00, but the calendar does move.
