ADDITIONAL SYSTEM INFORMATION :
OS - Windows 10 20H2
Java (JRE) - 11.0.12
JavaFX - 17.0.1

A DESCRIPTION OF THE PROBLEM :
The "scrollTo" feature on ListView is no longer working on JavaFX 17 or 18 early access builds.
It works fine if I downgrade to JavaFX16
It neither sorts by index nor by the object

countriesListView.scrollTo(lastSelectedIndex);

REGRESSION : Last worked in openjfx 16

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Create a list view in JavaFX
Insert 15-20 elements, such that you get a scrollpane on it.
invoke
listView.scrollTo(10); //Scroll to 10th index i.e. 11th element

Launch the program and you'd notice the list didn't scroll to the selected element (scrollTo doesn't work)

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
List View should scroll down to the given index/element in listView.scrollTo() method call.
ACTUAL -
listView does not scrollTo the given index/element and the focus is always at the beginning of the listView i.e. the first element

CUSTOMER SUBMITTED WORKAROUND :
Use JavaFX 16
