How to get the popover arrow to the left of the popover list?

I have a popover opening by a select. When the popover opens, the arrow displayed in ios is displayed on the top of the popover. How can I get the arrow to the left side of the popover?

<ion-select interface="popover">
  <ion-option>Test</ion-option>
  <ion-option>Test2</ion-option>
</ion-select>

Please show a screenshot of the current state you have.
