Pages like a component in browser

Hello everyone,

In my app im using two layouts, one for mobile and other for browser. On a particular page im using tabs to navigate between two pages, but in browser environment i would like the two pages to appear together in two columns.
For this i tried something like this:

<ion-tabs *ngIf="deviceCtrl.isMobile;else desktop">
        <ion-tab [root]="tab1Root" tabTitle="Pageone" tabIcon="contacts"></ion-tab>
        <ion-tab [root]="tab2Root" tabTitle="Pagetwo" tabIcon="list"></ion-tab>
<ng-template #desktop>

In mobile its works fine, but in the browser appear blank page without error message.

I expected that behavior works like customizable components, this dont work because the pages has @IonicPage()? How can i make it work like a component ir browser or like a Ionic page in mobile?

Thanks in advance.
