I am setting the CSS for Stackedbarchart . initially chart perfectly showing CSS colors for bars . but if i refresh the data set (i am creating new data set which has changes in y values only and setting it to chart), chart is not considering the css colors, its showing some random colors for each series.

steps to reproduce .
use any sample /Ensamble
set a style for chart bar / series with CSS .
recreate the chart data and reset the chart data using chart.setData()

chart will assign random colors.
