dragging object does not trigger blur event upon dragging

dragging object does not trigger blur event upon dragging

I have a focusout event listener attached to a form field which is triggered anytime i click or tab outside of the form field however, it is not triggered if i drag one of the dragging items I have on the page. The drag action seems to cancel the events previous to the drag. Is this by design and can it be configured to prevent this default behavior?
