Short description of the problem:

Cannogt hide NavBar with tabs on ionic 2 (sidemenu is okay)

What behavior are you expecting?

Remove navbar section should be able to hide the NavBar on pages with tabs setup on ionic 2

Steps to reproduce:
Only a few steps as below to create the MVP and reproduce the problem, you will see the screen did turn landscape for 50ms and then change back:
Install ionic 2 (http://ionicframework.com/docs/v2/getting-started/installation/):
npm install -g ionic@beta

Create a project (http://ionicframework.com/docs/v2/getting-started/tutorial/):
ionic start MyIonic2TabsProject tabs --v2

Remove this on a page:

<ion-navbar *navbar>
  <ion-title>Yo</ion-title>
</ion-navbar>

Run
ionic build ios
then this if you don't have an iPhone plugged in:
ionic emulate ios
or this if you have an iPhone plugged in:
ionic run ios

Just adding hide-nav-bar="true" to a view element in the v1 tabs example works fine, but no dice in v2. Googling turned up pages of folks having the same issue, with lots of hacks that I can't get to work, at least not in iOS.
