ScrollTrackExtent is the width of the scroll track used to navigate between the tab items. The scroll track is only displayed when the Thumb enum is included in the ScrollButtonTypes property. The ScrollButtons property is used to determine when the scroll buttons should be displayed. By default, they are only displayed when there isn't enough room to display all the tab items.
