Disable mouse over scroll in autocomplete

Question

I have a list like the scrollable result example.

Link: https://jqueryui.com/autocomplete/#maxheight

In this example, when we place the mouse on the last option, the scroll bar automatically descends. I would like to disable this, is it possible?

I tried to apply events directly to the list items but I wasn't successful, I imagine I'm going to the wrong place.
