duplicate row labels re-aligns entire row labels

[bapoorva]

I am aware that d3 heatmap uses rownames as default rowlabels. However, on choosing a column having duplicate values as row labels, d3heatmap displays it only once and moves the rest of the labels. For instance, in the image attached, the seven rows from the bottom are genes Dcc through Hcn1 and all the rows after are Snord116 (Snord116 is repeated 31 times). They appear to be labelled incorrectly. Is there anyway to fix this ?
