AttachedCardShadow with InnerContentClipMode == CompositionMaskBrush isn't correctly resized when the UIElement it's attached to changes size

[Ryken100]

Describe the bug

When AttachedCardShadow.InnerContentClipMode is set to CompositionMaskBrush, and the size of the element it's attached to changes, the shadow isn't properly resized to match.

Reproducible in sample app?

• This bug can be reproduced in the sample app.

Steps to reproduce

1. Create a new blank UWP app.
2. Add a `Rectangle` to `MainPage.xaml`.
3. Attach an `AttachedCardShadow` to the `Rectangle` and set `InnerContentClipMode` to `CompositionMaskBrush`
4. Implement some way to change the size of the `Rectangle` (e.g. have it change size on click)
5. Observe that when the size of the `Rectangle` changes, some of the elements that make up the shadow do not change size to match, leading to a glitched appearance.

Expected behavior

All elements of the shadow should change size to match the UIElement it's attached to, without a glitched appearance.

Was able to reproduce in the sample app with some tweaks to the implicit animation sample

            SampleController.Current.RegisterNewCommand("Size Element", (sender, args) =>
            {
                if (_element is FrameworkElement fwe)
                {
                    fwe.Width = _random.Next(200) + 100;
                    fwe.Height = _random.Next(200) + 100;
                }
            });

And using a Rectangle over a Border without the Canvas see #4739
