Ionic Framework Version

v8.x

Current Behavior

Switching between months in the calendar component is always happening with an animation, even if you have turned off animations in your application.

Expected Behavior

Switching to a month should happen without an animation.

Steps to Reproduce

1. Disable animations on the root component or application

@NgModule({
  declarations: [AppComponent],
  imports: [BrowserModule, IonicModule.forRoot({
    animated: false // Disable animations globally
  }), AppRoutingModule],
  providers: [{ provide: RouteReuseStrategy, useClass: IonicRouteStrategy }],
  bootstrap: [AppComponent],
})

2. Add an component with a date presentation

<ion-datetime
  presentation="date"
  displayFormat="DD-MM-YYYY"
>
</ion-datetime>

3. Switch between months. The new month slides in, even with animations turned off.

Additional Information

Looks like the scrollTo code needs to be adjusted https://github.com/ionic-team/ionic-framework/blob/c3ad15b0bf30fa8af1f8605962dca6e3f76e6fb3/core/src/components/datetime/datetime.tsx#L1478-L1482
