WinUI Scrolling Bounces, Regardless Of Accessibility Settings

### Describe the bug

If users use a touchpad to scroll in WinUI apps, and they reach the end of the scrolling container, it continues and bounces back, which can cause headaches and dizziness.

Turning Settings > Accessibility > Visual Effects > Animation Effects off does not stop this bounce effect.

I'm unable to use wheels, rollers, balls, etc. so can't see if they have the same effect.

### Why is this important?

It makes it harder to scroll these apps without headaches and/or dizziness.

### Steps to reproduce the bug

1. Go to Settings > Accessibility > Visual Effects and turn Animation Effects off.
2. Open WinUI 3 Gallery
3. Use the touchpad to scroll in the Gallery.
4. If you reach the top or bottom, it will have a "bounce" animation.

### Actual behavior

If you reach the top or bottom while scrolling, it will have a "bounce" animation.

### Expected behavior

If you have disabled Animation Effects, it should not have this animation.

Related to bug 13228. Possibly regressed by bug 7874.

### NuGet package version

None

### Windows version

Windows 11 (24H2): Build 26100

### Additional context

_No response_

Reproduce the bounce in WinUI 3 Gallery with Windows Animation Effects disabled, then compare the behavior with related bugs 13228 and 7874. The issue names no source files or tests; done means the touchpad no longer shows the bounce at scroll boundaries when animation effects are off.
