Comment (by WraithKenny):

 Problem is that the tab element's css height is calculated to be 16.2px
 (by firefox, opera, etc.), combined with any prior elements of a
 fractional pixel heights, causes the border to be displayed at the nearest
 pixel. When that pixel is higher, the border is shown. The border is only
 ever hidden because the white background of the li overhangs by (usually)
 a pixel. I can replicate on Mac and Windows.
