This has spawned from https://bugzilla.xamarin.com/show_bug.cgi?id=28277. While investigating #28277, I noticed that adding an item to the ItemsSource of a ListView does not behave as expected. It has a strange animation while inserting and does not show the newly added item at the bottom of the list. When all row heights are uniform, things are working as expected.
**Steps to Reproduce:**
1. Run the attached sample on iOS simulator
2. In the first tab, press Add Item
See screencast: http://screencast.com/t/Ngk1XS7nY
There is a visual animation that seems to be the entire list reloading. Then, it is not offset to the right position for the newly added row anyway.
Exactly the same results as adding an item when all rows are uniform. Only that row should animate into the bottom of the UITableView.

**Build Date & Platform:**
Use the Second Tab of the sample project to see the desired results and how it behaves when all rows are uniform.
Any update on this bug? This is holding up my release. Thank you.
