Disableing on-select-option not working

When using ion-select with inteface=“action-sheet” the disable property of the ion-select-option is not working:

<ion-select  interface="action-sheet">
          <ion-select-option [disabled]="true">1</ion-select-option>
          <ion-select-option [disabled]="true">2</ion-select-option>
          <ion-select-option>3</ion-select-option>
</ion-select>

In that cas the first and the second options should be disabled but they are enabled and the user can interact with them.
