Don't know if it is the intended behavior but all 3 options in the "Tools" list (Remember and focus the last selected folder, Automatically Scroll to selected folder and Automatically close other folders) when activated make the non-selected folders to be closed. In other words "Automatically scroll to selected folder" and "Remember and focus the last selected folder" cause the same behavior as "Automatically close other folders".
