Cropper instance created twice when recreate after destroy

[supachailllpay]

Current behavior

In my application I use cropperjs inside modal. When modal pop up I initialize cropper instance with:

cropper = new Cropper(image)

then If user close modal, I will destroy it with:

cropper.destroy()

So if user open modal again it will initialize cropper instance again except sometime cropper instance has created twice.

Minimal reproduction of the problem with instructions

I create jsfiddle, click toggle (or re-run) over and over you will see two cropper instances.

Browser:

• Chrome (desktop) version 64

My debugging

After debugging I found start method had called twice which I think one come from normal behavior and another one come from load listener which (If I understand your code correctly) it should destroy in start method here.

In pervious version(v1.2.2) everything works fine, this behavior just appear in new version (v1.3.0). So I look into files changed between 2 versions and found this.

In my opinion I think set onload to null cannot remove listener from addEventListener.

I hope this information will help you.
Thank you.
