It consist in 3 pages: HomePage, Popover (for the component) and PushedPage.
When pushing a page in the Popover .ts file after using viewCtrl.dismiss() it simply pushs the page off the navigation stack and off the <ng-component>. Also the statusbar goes over the header, like it was a component of the page with position: absolute and top: 0.
Using it without the viewCtrl.dismiss() is fine.
The problem doesn't occurs only in the first page, every page pushed after it will have the same behaviour.
In home there'll be a button in the page and a menu button in the header, whose opens the popover.
Open any browser dev tools, inspect the elements and open the <ion-app> tag.
Try pushing a page from the popover clicking in Push with Dismiss. PushedPage is pushed after ng-component, not inside of it and the problem is shown.
Clicking in Push without Dismiss or Push page button everything is fine.
Build for iOS to see the navbar issue, since it only occurs in iOS.
