[WinUI]ArrangeOverride is not being called on invoking its Arrange method

Question

Is there any chance ArrangeOverride notification could get skipped on invoking its Arrange method.

Code Snippet:

class Parent : LayoutPanel
{
..........
    private void method()  --->// any method 
    {
        child.Arrange(new Windows.Foundation.Rect(50,0,100,100));
    }
..........
}

class child : LayoutPanel
{
.......
    protected ArrangeOverride(Size finalSize)
    {
    }
.......
}

While invoking Parent.method(). Despite the fact that the former location is not same (0,0,100,100), child.ArrangeOverride() is not being called.
