Placement position of item when moving from one column to another in multiple lists

Regarding multiple lists and using this example taken from Storybook.

Let's say there's a column with only one item, if you drag another item into that column to place in the last position but drag down a little further it looks to place this item at the top of the list.

Seems to work correctly (i.e placing the item in the last position) when the column has a certain number of items (perhaps relative to the height of the column).
