Going back when click center on drilldown feature

[MuhammedAlmaz]

I this issue #81 there is an example about drilldown component. When i check this example https://codepen.io/stockinail/pen/mdLPRmY there is a bug. Look when you click the center of component it going to back but it should go inner the clicked object items.

@kurkle I'll do my best because very busy in another project. Nevertheless, @MuhammedAlmaz having a quick view, I see that the event area seems t be wrong and it doesn't match against the rect dimension. Seems to be a bug
