[UIElements/UI Toolkit] One extra item is added to the ListView when a ListView is bound to a SerializeReference List
How to reproduce:
1. Open the user's attached "bug-uielements-list-binding.zip" project
2. Open the "scene" Scene
3. Select the "Tests" GameObject in the Hierarchy window
4. Observe the Inspector
Expected result: ListView and the bound SerializeReference List have the same amount of items
Actual result: ListView has 3 items while the bound SerializeRefence List has only 2 items
Reproducible with: 2019.4.8f1, 2020.1.3f1, 2020.2.0a21
Could not test with: 2018.4.26f1 (UI Toolkit is not available)

- Channel remapping dropdown in the Terrain Layer does not open when clicked on the title
- The Editor freezes indefinitely when a large number of elements are entered in the Subgraphs or Categories lists
- Some Visual Effects package Assets links to documentation are not working
- Heatmap asset’s documentation button in the Inspector window leads to “Sorry... that page seems to be missing!” page when clicked

Resolution Note:
This behaviour is currently by design in the ListView binding. However you can easily disable it by setting the showBoundCollectionSize property of ListView instance to false.
