According to this page, it says that "Nested frames are supported, enabling hierarchical navigation scenarios."

How is this achieved, especially in XML markup?

I've tried nesting a Frame tag inside a root Page tag, with a Page tag inside of it with a Label tag inside of it, but it doesn't show anything except for an empty extra action bar for iOS and a cannot read property 'getLayoutParams' of undefined on Android.

<Page xmlns="http://www.nativescript.org/tns.xsd">
  ...
  <Frame>
    <Page><Label text="Hello?" /></Page>
  </Frame>
  ...
</Page>

TNS 1.4.3.
