### Overview
On Windows Phone, a RelativeLayout inside another RelativeLayout will always be visible when it is first rendered even if IsVisible = false.

### Steps to Reproduce
1. Run the attached Windows Phone project

### Expected Results
The blue RelativeLayout will not be visible.

### Actual Results 
The blue RelativeLayout is visible even though IsVisible is set to false in XAML. The button is supposed to toggle between visibility states, but the first press does not hide the layout. Only after subsequent presses does the layout’s visibility toggle. This makes me think that the issue is the native FrameworkElement not being in sync with the RealtiveLayout’s IsVisible property.

### Workaround
Use a custom renderer for the inner RelativeLayout and inside OnElementChanged() set

> this.Visibility = Visibility.Collapsed;

### Environment
Reproduced the issue with Form 2.0.0 and 2.0.1-pre1. However, the issue doesn’t exist in version 1.5.1.
