Xojo2024R1: vertical scrollbar out of synch when using cursor keys of the keyboard to navigate list

It looks like unfinished work on WebListBox, trying to navigate list with cursor keys (up/down) from keyboard does not move vertical scrollbar. This is on MBP M1 and Safari. Easy to replicate using build in Listbox example too.
