Unwanted scroll on click on last item in ItemsControl - wpf

Question

Case: ItemsControl with Virtualizing enabled (performance). Contains checkboxes/textboxes/etc. However, clicking on checkbox/textbox on last visible item causes itemscontrol to scroll down instead of selecting the checkbox/textbox.
With virtualizing disabled, everything works fine...
I have tried a lot of things (using ListView, wrapping it in larger panel, etc.). No luck.
ItemsSource is set in code behind to a large dataset of testitems with properties Name and ID.
