tooltip mislabeled when zoom in [Firefox]

[houndcl]

I tried your example: http://rpubs.com/jcheng/mtcars-heatmap. It works perfectly in the global view. However, the tooltips don't show the corresponding row and column info when zooming in the heatmap. It seems it's a bug for Firefox (tested on ver42.0). IE works. I haven't tested on Chrome.

I can confirm the issue with Firefox 42.0 (Windows). Works OK with Chrome.

Still wrong when zoomed in using Firefox 45.0 (mac). Works fine with Safari (9.0.3)
