Crash in ListView when scrolling with pen

[anawishnoff]

Describe the bug

When scrolling the ListView sample in the WinUI 3 Controls Gallery with a pen, a crash occurs.

The crash results from an E_ACCESSDENIED return from the API used for touch and pen drag and drop. It's not clear why a drag and drop operation is being attempted in this repro -- I only scrolled with the pen; I didn't perform the touch and hold gesture to start a drag of the list view.

Consequently using drag and drop to re-order the list view with pen does work, it's just scrolling that causes this crash.

Steps to reproduce the bug

Repro Steps:

1. Install and run latest WinUI 3 Controls Gallery
2. Open the first ListView sample.
3. Scroll the list view with a pen.

Result: Crash
