isOver impacts all Droppables

[maxsalven]

I have a basic a calendar where each Day is a Droppable. However if I drag an item onto any day, then ALL Droppables think isOver is true, when only the Droppable I'm hovering over should have isOver === true.

I discovered there is an undocumented id prop on Droppable which fixes this.

Ah, yes that should be better documented. Thanks for filing this issue. I'll add this to the backlog to update the documentation.
