Describe the bug
derived ItemsRepeater, used in conjunction with a UniformGridLayout, subcribed to ItemPrepared / ItemClearing events and calling back the relevant element's datacontext viewmodel to allow for thumbnail loading / unloading when the element is prepared / cleared... The issue is just with item zero in the ItemSource. I'm not sure if it's the element not being recycled properly or if its datacontext property is not setup correctly at the time of these events, but it appears item zero immediately prepares again after being cleared, and clears again after being prepared.
To Reproduce
I made a demonstration project here : https://github.com/philvanzu/VirtualizingItemsRepeaterBugDemo.git. Build it, run it, scroll down until you see a log of item zero being recycled, then scroll back up to the top and you should see item zero not being loaded as it should be. Built and tested on Linux (CachyOs) with JetBrains Rider and Avalonia 11.3.
Expected behavior
Item zero should be loaded correctly after scrolling down until it recycled, then scrolled back up until it is re-prepared
Avalonia version
11.3.1
OS
Linux
