[Bug] TabView UWP screen resize shows other TabViewItem's content

[Estevete]

Description

Running the app in UWP with a TabView, resizing the window (making it bigger) will show the next TabViewItem's content.

Steps to Reproduce

1. Run Xamarin.Community.Toolkit.Sample.UWP project (or create a new one using TabView with some TabViewItems)
2. Open any view

Content should fit the window, without showing the rest contents unless you switch tabs.

Actual Behavior

The rest of TabViewItem's content are showing, depending on how much you make it bigger.

Also to note, the tab strip will not resize either.
I did see parts of the tab strip resize once or twice, but different elements like the selected bar and the text/icons etc did not resize at the same rate.

Scrolling with fingers are not possible. TabView simply does not work on UWP
