Using SfListView with Realm DB does not work as expected when updating data in Realm

Attaching solution with a bug. It has 2 lists, regular Xamarin's and SfListView. Regular list works as expected.

RealmDB queries are live - when you update the data in Realm, queries are updated automatically. Normally, it's automatically reflected in lists with data bindings. The issue happens when you update the properties on the Model, which results in removing the item from the query. However, in SfListView the item stay on screen, even though all corresponding events  (collection item delete event) have been fired correctly.

The issue happens on both platforms, however in a bit different way. If you add a lot of items to the list, so "bad" items will go off screen, the labels on those "bad" items disappear on iOS but stay on Android.
