Tab doesn't work correctly with CollectionView on Windows platform

[systemloc]

Description

Tab will typically cycle through various text entry controls, but this appears to be broken when placing multiple controls in a CollectionView. Referring to the sample XAML below, if a 3 element array is created and a CollectionView containing an Entry control is created, then 3 entry controls will be displayed, but you can't use the tab key to iterate the focus through them. In contrast, if you place several Entry controls in a VerticalStackLayout or Grid, then tab can be used to iterate through the focus as expected.

Reproduction code creates a two column grid, one with a CollectionView containing 3 Entry controls, and one column containing a similar VerticalStackView containing 3 Entry controls. Tab will iterate through the VerticalStackView as expected, but doesn't for the CollectionView.

Steps to Reproduce

Sample XAML code to demonstrate the bug:

<CollectionView Grid.Column="1"> <CollectionView.ItemsSource> <x:Array Type="{x:Type Color}"> <Color>Red</Color> <Color>Green</Color> <Color>Blue</Color> </x:Array> </CollectionView.ItemsSource> <CollectionView.ItemTemplate> <DataTemplate> <Entry FontSize="12" HeightRequest="50"/> </DataTemplate> </CollectionView.ItemTemplate> </CollectionView>

This threw me when I first encountered it, but it kind of makes sense when you break it down; when you Tab to the CollectionView its selection takes over - you should be able to move between items with the arrow keys. Consider CollectionView is more geared up for selecting an item rather than just dynamically displaying N items. I suspect that BindableLayout on a VerticalStackLayout might be more what you're looking for.
