CPP WinAppSDK app crashes when dragging ListView scroll bar

[stefansjfw]

Describe the bug

When having nested Grid in ListView.ItemTemplate (not 100% confirmed), after some ListView item is updated (any property changed) dragging ListView's scroll bar causes app to crash. This only happens when ListView has many items (> few thousands).

It sometimes crashes right away and sometimes after scrolling up and down. Check the attached gif.

Steps to reproduce the bug

1. Clone and run https://github.com/stefansjfw/winappsdk_cpp_crash_example.git

Crashing scenario: 2. Press 'click to change the first item in the list' button 3. Dragg ListView scroll bar up and down until app crashes

Non-crashing scenario: 2. Dragg ListView scroll bar up and down and observe that app doesn't crash

Expected behavior

App doesn't crash
