In some cases, the auto-scrolling (inside the table) to the
position of the marker, when the user switches between MarkerA
and MarkerB can be very annoying. This patch disables this
vertical auto-scrolling. Jumping to the position of the Active
marker is still possible, but the user has to do a second
click on the MarkerA/MarkerB button.
