There is a definite issue with the data point selection support. My data series has some selectable and some non selectable data points. I select the data points with a mouse drag to select few points. Now if I try to unselect them by clicking on them then they don't get unselected. However if I stick to the same method for unselect i.e. to drag the mouse again then the points get unselected.
Also note that the behaviour is observed only when the data series has a combination of selectable and non selected points. If the entire series is selectable then the issue is not observed.
On deeper analysis I found out that actually the unselect event is getting triggered and the point is no more in the selected list but the circle which surrounds the point stays there. Hence it is an issue with the select circle.

Here is the Stackblitz demo and the code. #c3-chart-error
Here all points above 5 are selectable. Please follow the below steps to reproduce the issue.
