[MAUI] ListView rendering issues when binding the IsVisible property.

[samhouts]

Description

Items being replaced (removed and re-added) to a bound observable collection do not render completely after being added when the IsVisible property is changed via a binding. 

Expected vs actual:

Steps to Reproduce

1. Open attached test project
2. Deploy to Android emulator (tested on API 34)
3. ListView starts invisible.
4. Items will be added on a timer every 5 seconds. 
5. Watch console output for items count and observe the ListView.
6. It should become visible and the first item render completely in 5 seconds.

Expected result:

Every item added to the ObservableCollection will render completely in the ListView and remain visible unless removed. 

Actual Result:

Only the yellow box shows on the newly added item. If you scroll the ListView manually, the ListView then renders correctly, but the next added item will again be just a yellow box and no more items will appear until ListView scrolled.
