After some discussion with the Angular team, this looks like something we need to address inside of Ionic: https://github.com/angular/angular-cli/issues/21682

Ionic was leveraging a defect in zone.js which caused async operations to not be intercepted, resulting in this issue. It was technically an issue before this thread was opened, but we never noticed it until now because native async/await was not previously downlevelled.

I will look into a fix soon.

I applied a workaround to this problem for now, After setting the value of the select if you add “item-has-value” class to parent item element of the select in a setTimeout function, the things works somehow as expected.

@ViewChild(‘item’, { static: false }) item: any; … setTimeout(() => { this.item.el.classList.add(‘item-has-value’);
}, 100);

 <ion-item #item>
  <ion-label position="floating">
              label
            </ion-label>
            <ion-select></ion-select>
</ion-item>
