mouse event accuracy

I am noticing that in a large dense graph (1K+ nodes, 10K+ edges) the mousenter and click events are being fired inaccurately. That is even when I am outside a node mousenter is getting fired. Similarly I click on one one and the adjoining node is receiving the click event. It is like the accuracy of the mouse location is a bit off. Is this a known issue and is there a fix for this?

thx

Start by reproducing the inaccurate mouseenter and click behavior in a graph with 1K+ nodes and 10K+ edges, then inspect the event-handling entry points. Compare the reported pointer location with the node receiving each event; done means events target only the node under the pointer, or the issue is narrowed to a documented cause.
