Current Behavior

• Simple use case: show popup with a loading indicator, wait for a second, hide the indicator and show some long text.

    <Border BackgroundColor="White" x:Name="RootBorder" Padding="20">
        <Border.StrokeShape>
            <RoundRectangle CornerRadius="12" />
        </Border.StrokeShape>
        <StackLayout Orientation="Vertical">
            <ActivityIndicator x:Name="LoadingActivityIndicator" WidthRequest="50" HeightRequest="50" HorizontalOptions="Center" IsRunning="true" IsVisible="true" />
            <Label x:Name="LabelContent" LineBreakMode="WordWrap" />
        </StackLayout>
    </Border>

The result is broken:

• Word wrap does not take Border's padding into account
• Border does not completely expand

Expected Behavior

• Border expands
• Word wrap takes Border's padding into account
