I have a real time updated chart and users can add annotation to the chart. The position of the annotation will be updated with the chart data. I would like to stop updating the annotation position while user dragging the annotation. So I added a flag (e.g. isDragging) to the annotation dragStarted and dragEnded events. The isDragging flag will be set to true in dragStarted and then set to false in dragEnded. I will check this flag before updating the annotation position.

Here’s the problem, the annotation dragStarted event will be triggered when users do panning in the chart. But the dragEnded will not be triggered in this case. It breaks my plan to stop updating the annotation position as the isDragging will be incorrect. Is it a bug that the annotation dragStarted event (but not the dragEnded event) triggered when panning?
