To reproduce, enable the colormap for one particle group. Then go to the second particle group and change the colormap variable. the second particle group's colorbar will appear even though you have not enabled colormapping.
This does not occur if colormapping is disabled for all particle groups, however, if you enable colormapping for any of the particle groups then both colorbars will appear.
This suggests that when colormapping is disabled for all particle groups that the colorbar(s) are being appended to the div but since the width of div is 0 you don't see it.
