Popups on charts sometimes stop working

[62mkv]

sometimes, although quite frequently, when a chart (say, vertical bar chart) is initially displayed, it displays labels on hover quite fine. However, if I begin to refine dataset and/or view, like switch from stacked to grouped, or detalize/undetalize a dimension level, labels stop working and not come back again

is this expected behaviour?

version 2.0.3-devel

I've seen this happening in this and other projects with nvd3.js. I believe that latest nvd3.js version behaves better regarding tooltips.

Action plan: upgrade to latest nvd3.js and try to review tooltip behavior.
