Using draggableElem.unset() ondrop

[nishirken]

Hi
I'm using interactjs in my React project for dnd emulation though pointer events from this library. But encountered with problem.
If I use .unset() on draggable element unmount during drop process, I got an error.
I reprodused it with pureJs: https://codepen.io/nishirken/pen/LYWzNYK

Expected behavior

interactable should be handled before fireEvent call, or events dispatching process should be terminated for elem, which doesn't have interactable instance.

optional call this.interactable?.fire(iEvent) seems to be the simplest solution.

Actual behavior

error

System configuration

interact.js version: 1.10.11
Browser name and version: FireFox Developer Edition v89.0b15 (64-bit)
Operating System: macOS 11.4
