bug: datetime, ios only, looping between months when disabled is set

[mcvendrell]

If you set disable in the ion-datetime component, the "old" bug of "change automatically to previous selected month" happens (only on iOS).

Steps to reproduce:

1. Set a calendar
   <ion-datetime
   #calendar
   presentation="date"
   [firstDayOfWeek]="1"
   [disabled]="loading()"
   (ionChange)="dayChange($event)"
   [(ngModel)]="selectedDate"
   />

2. selectedDate is null by default

3. Change to a new month and select a new day.

4. When ionChange, simply do a call to any process consuming time and set a signal to loading.set(true) before load

This will make datetime to go a previous month.

Changing the selected month and clicking on a new day causes the component to go back to previous month and date, no matter the month. This problem happens on iOS only. I tested on iOS 18.5 (real device) and on iOS 18.4 (emulator).

"@capacitor/splash-screen": "^7.0.1",
"@capacitor/status-bar": "7.0.1",
"@capawesome/capacitor-android-edge-to-edge-support": "^7.2.2",

Works fine in Android/web.

As a workaround, I set a div with transparency over the calendar to emulate the disabled state.
