Weird Hit testing after scaled with Composition animation

[HO-COOH]

Describe the bug

I found that after applying a composition animation to scale up a ui elements (eg. Button), they are no longer correctly hit-tested.

Why is this important?

It's confusing to user.

Steps to reproduce the bug

1. In winui 3 gallery, go to Animation Interop page
2. Hover over to the button in the first example, it will be scaled up
3. Move the cursor and click on the bottom right corner of the button.
4. The clicked state is very inconsistent. It will seemingly switch to normal state while you are still holding the mouse button.

Actual behavior

No response

Expected behavior

After scaled its visual, it should either participate in hit-testing according to the new size, or, participate in hit-testing with the original size.
