WebView2 scrolling with Precision Touchpad is less responsive than Edge in WinUI/UWP

Nobody has claimed this yet.

### Describe the bug

When using WebView2 hosted in a WinUI 3 or UWP application, scrolling with a Windows Precision Touchpad feels noticeably less responsive than in Microsoft Edge, even though both use the same WebView2/Edge runtime.

The issue is easy to notice on long web pages such as GitHub, Wikipedia, or other scrollable websites. Compared with Microsoft Edge, the content appears to lag slightly behind finger movement, making scrolling feel less direct and less "attached" to the touchpad gesture.

This behavior is consistent across different websites and is reproducible every time. The same pages scrolled in Microsoft Edge on the same machine feel significantly smoother and more responsive.

Expected behavior:
Scrolling in WebView2 should feel as responsive and smooth as scrolling in Microsoft Edge when using a Windows Precision Touchpad.

Actual behavior:
Scrolling in WebView2 has slightly higher perceived input latency and reduced responsiveness compared to Microsoft Edge, resulting in a less natural scrolling experience.

If this behavior is expected because of the current WinUI/UWP hosting model, could you clarify whether there are any recommended APIs or configuration options to achieve scrolling responsiveness comparable to Microsoft Edge?

### Steps to reproduce the bug

Scroll within any WebView2 interface.

### Expected behavior

Content scrolls with your finger.

### Additional context

_No response_

Reproduce the behavior in a packaged WinUI 3 or UWP app on Windows 11 24H2 with WebView2 package version 2.2, using a long page such as GitHub or Wikipedia. Compare Precision Touchpad scrolling with Microsoft Edge on the same machine, then determine whether the difference has a documented API or configuration option; done means a reproducible cause or a clear supported recommendation.
