Pushed page don't overlap the last one completly

Ionic Framework ionic-v3
1

I’m pushing a new page (RelationshipPage) over the rootPage (HomePage) that contains the elements <ion-header>, <ion-tabs> and <ion-content>.

When the RelationshipPage opens, your elements <ion-header> and <ion-content> doesn’t overlap completely the HomePage and only the <ion-tabs> element stays in view with the RelationshipPage elements.

Anyone can tell me what I probably misunderstood that only the <ion-tabs> element stays is in view?

PS.: I’m using RC.3 version.

Thanks!
