Cursor not-allowed arePiecesDraggable and onPieceDrop not triggering

[loisperrigon]

Hello,

First of all, thank you very much for your work on this library. It’s incredibly useful and well designed!

However, I noticed an issue. When I drag and drop a piece, a "not-allowed" icon appears. If I accidentally drop the piece before the icon disappears, the logic in the onPieceDrop prop is not triggered.

Initially, I thought the issue might be in my own code. However, I was able to reproduce the same bug on the website mentioned in the README:

It seems that when the drop happens too quickly, the logic in onPieceDrop is not executed.

Could you please look into this? Thank you!
