Tabs and refresher

I’m using ionic tabs component and refresher component.
Code is like this:

  <ion-refresher (ionRefresh)="doRefresh($event)">
  <ion-tabs tabsPlacement="top">....</ion-tabs>

When tab root page has long content and i scroll it up by pulling down, refresher starts working instead of scrolling tab content.
Is there any way to fix this problem? Except placing refresher inside tab root page.

Thank you,
