You can see in this bl.ocks that when you mouseover a feature, a tooltip should inform about its data. Also a circle will overlay. If you click an alert should fire.
The question is that with latest versions of Firefox and Safari everything is OK. Is Chrome who gives problems.
Even if I only set up a much more simple interaction event (onmouseover just console.warn('mouseovering')), Chrome is not able to detect the features correctly.
So I think it's more about a tile positioning in Chrome (?), that unables to correctly find the circles and associated JSON.
Quite a weird issue. Thanks in advance
