When the last visible tab is focused, there is no indication that there are more tabs available in the TabPane. Because of that, it would be good if a tab next to the last visible tab is partially visible.

For more information, see attached screenshots.
[1] TabPane shows only two tabs; the first tab is selected.
[2] Current state - when the second tab is selected, the first tab is partially visible. Note that there is no clue that there is also a third tab in the TabPane.
[3] Desired state - when the second tab is selected, the first and third tab are partially visible.
