Changing color of SolidColorBrush don't cause a rerender

Describe the bug When i change Color property of SolidColorBrush in resources it doesn’t cause a rerender. It works in 11-preview*, but doesn’t work in rc1-1

To Reproduce Steps to reproduce the behavior:

1. App.axaml:

<Application.Resources>
    <SolidColorBrush x:Key="MyBrush" Color="Aqua"></SolidColorBrush>
</Application.Resources>

1. Window:

<StackPanel>
  <TextBlock Foreground="{DynamicResource MyBrush}">TEST TEXT</TextBlock>
  <Button Foreground="{DynamicResource MyBrush}" Click="Button_OnClick">CHANGE COLOR</Button>
  <Button Foreground="{DynamicResource MyBrush}">DUMMY</Button>
</StackPanel>

1. Code behind:

private void Button_OnClick(object? sender, RoutedEventArgs e) {
    var solidColorBrush = App.Current.Resources["MyBrush"] as SolidColorBrush;
    var random = new Random();
    solidColorBrush.Color = Color.FromRgb((byte)random.Next(0, 255), (byte)random.Next(0, 255), (byte)random.Next(0, 255));
}

Desktop (please complete the following information):

if you change the code like this

        private void Button_OnClick(object? sender, RoutedEventArgs e)
        {
            var random = new Random();
            App.Current!.Resources["MyBrush"] = new SolidColorBrush()
            {
                Color = Color.FromRgb((byte)random.Next(0, 255), (byte)random.Next(0, 255), (byte)random.Next(0, 255))
            };
        }

works.

Yes, i think it related to your issue, @danipen

But i facing this issue only for rc1-1, not for preview*. I should check it again.
