Describe the bug

The ColorPicker control in WinUI 3 doesn't update itss value if the initial value is set to argb #FF000000.

Steps to reproduce the bug

1. Create new WinUI 3 project. In MainWindow.xaml, set XAML:

<StackPanel Orientation="Horizontal" HorizontalAlignment="Center" VerticalAlignment="Center"> <ColorPicker Color="{x:Bind SelectedColor, Mode=TwoWay}" /> </StackPanel>

2. In code-behind:

public Color SelectedColor { get; set; }

var color = ColorHelper.FromArgb(255, 0, 0, 1); SelectedColor = color;

After launching, click anywhere in color palette and see only Black stays. Any value other than black works, including white. Same effect can be seen by simply setting the ColorPicker value to #000000 and clicking around.

Expected behavior

Black would follow same logic as other colors.
