Description

On Windows, with a ListView tied to an ObservableCollection, if an item is inserted in between two items, sometimes you end up with the display showing two items with the inserted value instead of two separate items. For example if you add "Test 1" then "Test 3", and then insert "Test 2" between the two items. The ListView will show:

Test 1
Test 2
Test 2

instead of what it should show:

Test 1
Test 2
Test 3

The ObservableCollection does have the items in the proper order, but the display is wrong.

Steps to Reproduce

(See the repro project)

1. Create a MAUI app.
2. Add a ListView to the main page.
3. Tie the ListView to an ObservableCollection.
4. Add a couple of items.
5. Insert 1 item between the two items.

Last version that worked well

Unknown/Other

Affected platforms

Windows

Affected platform versions

windows10.0.19041.0

Did you find any workaround?

It works properly with a CollectionView, but the CollectionView doesn't support the RowHeight property that I need.
