Project to reproduce this bug

Context: 
This is an issue on devices with a hardware DPAD (Tested on an Intermec CN51) 
Overview: 
We have been observing some wired behavior when navigating XF applications using the DPad on our CN51. Such behavior include instances where the focus seam to be "locked" in an invisible state preventing the user from navigating through the page.

I managed to reproduce such an instance by creating an application with two pages. The second page contain a label and two entry views inside a StackLayout: 

Steps to reproduce: 
1) Build and run the attached project on a device with a DPAD (tested on an Intermec CN51) 
2) click the button no navigate to the second page. 

Observed behavior: 
Pressing the up/down buttons on the dpad moves the focus between the actionbar back button and some view not visible. This makes it impossible to navigate the page using the dpad buttons. 

If an entry view is selected (using touch) the dpad can be used to navigate the page UNTIL the back button in the actionbar receives focus. After this point the navigation is again stuck between the back button and some invisible view. 

Expected behavior: 
using the dpad buttons should switch focus between the two input fields and the actionbar back button. 

Other Observations: 
If the two first views on the second page (the label and the first entry) is swapped the dpad work as expected.
