[Ionic 4 ] - ion-back-button is breaking Tabs View

ion-back-button is crashing the app when used with Tabs as it is setting history to be as /tabs where in it was actually tabs/(home:home).

<ion-header>
  <ion-toolbar>
    <ion-buttons slot="start">
      <ion-back-button></ion-back-button>
    </ion-buttons>
  </ion-toolbar>
</ion-header>
