Last item disappears when sorting

Hello.

When I move the last item to an other place, it renderers it, in the correct position, but it's "invisible".
If I try to place an item on top of this "invisible" item, that item is also becomes "invisible".

I tried to reproduce it in a snack, but I couldn't.
I checked, every item gets rendered after sorting. The strange thing to me, that it leaves exactly as much empty place as the component itself.

Did someone encountered similar bug?
