UWP XAML BladeView control - scroll newly-created BladeItem into view

Question

I'm using the BladeView control from Microsoft's Windows Community Toolkit. When the application window is < 640px, the BladeMode property changes to Fullscreen.

When a new blade is created in my code behind, I want the BladeView to scroll to the right so that new blade is displayed. It seems like I should be able to use StartBringIntoView() to accomplish this, but it's not doing anything.

Here's what I'm doing:

if (bladeView.BladeMode == BladeMode.Fullscreen)
{
    // current window width
    Rect windowBounds = Window.Current.Bounds;
    int currentWidth = (int)windowBounds.Width;

    // scroll to view
    BringIntoViewOptions opts = new BringIntoViewOptions();
    Rect target = new Rect { Height = windowBounds.Height, Width = windowBounds.Width, X = currentWidth, Y = 0 };
    opts.TargetRect = target;
    newBlade.StartBringIntoView(opts);
}

This is what my XAML tree looks like:

I just needed to use bladeView.UpdateLayout() before calling StartBringIntoView().

Example:

if (bladeView.BladeMode == BladeMode.Fullscreen)
{
    // update the layout so StartBringIntoView() works
    bladeView.UpdateLayout();

    // scroll BladeView to newly-created BladeItem
    newBlade.StartBringIntoView();
}
