Baseline showing on active tab when orientation on bottom
When Orientation is set to toTop, the baseline only shows beneath all tabs other than the currently active one. However, when Orientation is set to toBottom, there is still a baseline above the active tab. What's more, this baseline is not the same width as the main baseline. Across the span of the control, the thickness is 2, but a line with thickness of 1 also appears on the active tab.
I am 120% sure there is not another control, such as a panel, which is showing this line, because I see it in design-time too, with absolutely no other controls in the vicinity.
Thought I should probably include the tabs themselves:

NOTE: When changing LookAndFeel.Tabs.Active.Style.Outline... properties, this affects this line. If I change the OutlineSize to 1, this line disappears. It seems this line always shows 1 pixel less than OutlineSize.
