how to scroll ListView to make a specific item visible (only when not visible already)

[Tomas Mikula]

Hi,

does anyone know of a way to make a specific ListView item visible,
but don't scroll the ListView at all if the item is already in the
viewport?

I am working on a code editor, displaying lines in a ListView.
Whenever the caret moves up/down, I want to bring the current line to
the viewport.

Thanks,
Tomas

P.S.: To determine if an item is visible, I tried tracking non-empty
cells by listening to ListCell#emptyProperty(), but a non-empty cell
is not necessarily visible.
