List selection briefly highlights, but does not remain selected. How to implement in LVGL8.0

Description

It appears the default behavior of a list has changed.
When clicking on a value in a list, it momentarily shows focus, but then looses its focus.
I need for the focused state to remain, and then when clicking another item in the list, for it to receive focus, and the previously selected item to loose focus.

When returning to the list, I wish to have the last clicked item to be highlighted.

How do I achieve this, if at all possible?
