From a functional point of view, these small vertical dividers are important (so you know where to grab the border), but the horizontal bottom line has no practical function, other than an aesthetic one, and for some skins you don't want that horizontal border.
But it is impossible to 'remove' that horizontal line, without also removing the vertical divider lines.
My request is: either a separate element for the 'dividers', or perhaps make these dividers dependent on: id="Content[TrackDetail].Body.Default", which shares a similar and actual practical purpose:
