ListView or Grid not appearing when ContentPage inside PageViewContainer

[ckogevina]

When using a ListView or a Grid layout in a ContentPage which is placed inside a PageViewContainer the ContentPage appears empty (I've tested on Android).
The same ContentPage used outside the container displays fine. Is it something I'm doing wrong or is there a limitation on elements that can be used in a page placed inside a PageViewContainer?
Noticed that when calling PageViewContainer.Layout(....) the page contents appear as if the page is forced to repaint
