bug: IonDatetime view does not update after value changes

[tmwrnr]

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

• v4.x
• v5.x
• v6.x

Current Behavior

The component IonDatetime is not updating the UI changing the value. The value is handled by a state variable (useState).

This is only not working, if the presentation is set to month-year or year.

Expected Behavior

If the state variable changes, the component should update the UI.

Steps to Reproduce

function Example() {
  const [date, setDate] = useState(new Date().toISOString())

  const handleClick= () => {
    setDate((d) => {
      const year = new Date(d).getFullYear();
      const newDate = new Date(d);
      newDate.setFullYear(year + 1);
      return newDate.toISOString();
    });
  }

  return (
    <>
      <IonButton onClick={handleClick} >Click</IonButton>
      <IonDatetime presentation="year" value={date} />
    </>
    
  )
}

Thanks for the issue, I'm able to reproduce this. The underlying cause here is likely similar to #22868 since ion-datetime also uses a hidden input to keep track of the value. The fix may be slightly different due to the differing components, though, so I'll keep the two issues separate for now.

This looks to be the same as #26391, so I am going to merge the two.
