/* WebKit insets the thumb's centre by half its own width at each end of
   the track (it can never overflow the track bounds), but a gradient
   percentage stop has no such inset - so a fill positioned from raw
   value/max alone drifts up to 9px (half of the 18px thumb below) away
   from the thumb's actual centre, worst at the two ends and exactly
   correct only at the midpoint. calc() corrects for that inset the same
   way the browser's own thumb-position algorithm does. If the thumb's
   width below ever changes, both the "18px" and "9px" here must change
   with it, or this drifts again.
