[Android][iOS] ApplicationView.GetForCurrentView().VisibleBounds returns a Rectangle with all values set to 0

[takla21]

Current behavior

For instance, when having this logic to set the bottom bar

#if __ANDROID__ || __IOS__
        var full = App.Instance.MainWindow!.Bounds;
        var bounds = ApplicationView.GetForCurrentView().VisibleBounds;

        var bottomPadding = full.Bottom - bounds.Bottom;
#else
        var bottomPadding = 0;
#endif

        TestTextBlock.Text = bottomPadding.ToString();
        if (bottomPadding > 0)
        {
            SafeAreaRow.Height = new GridLength(bottomPadding);
        }

<Grid>
  <Grid.RowDefinitions>
    <RowDefinition Height="*" />
    <!-- SafeAreaRow.Height is set in code behind -->
    <RowDefinition x:Name="SafeAreaRow"
                   Height="0" />
  </Grid.RowDefinitions>

  <TextBlock x:Name="TestTextBlock"
             FontSize="20"
             VerticalAlignment="Center" />

  <Border Background="Red"
          Grid.Row="1" />
</Grid>

it looks like this

Expected behavior

ApplicationView.GetForCurrentView().VisibleBounds should return a Rect with the dimension of the screen excluding phone edges.

This feels similar to https://github.com/unoplatform/nventive-private/issues/510, what do you think @kazo0?
