Generates a CSS selector for the floating bars of a waterfall series.
A waterfall extends column, so each step is one .highcharts-point in

bars are a single path.highcharts-graph carrying no point class, so they
are already excluded — which is what MAIDR wants, since a connector only
repeats the running total the two bars it joins already announce.
