Stamped element can be overlapped by dragged element

[EnricoSottile]

Hello,
I'm keeping a few blocks fixed in position, so that calling layout() or adding/removing elements does not move them, while others shifts around.
It works correctly with the stamp method.

Adding Draggabilly break this behavior by overlapping.

Steps to reproduce:

1. init Packery and Draggabilly as outlined in the instructions
2. stamp a Packery element so that it's fixed in position
3. drag an item over it and release

Test case: https://codepen.io/anon/pen/arLByQ
(Only added stamping ability to the original demo: https://codepen.io/desandro/pen/aGvIq)

I understand there's no collision detection inside draggabilly, but this seems more a Packery related issue to me.
Thanks

Edit: The same problem happens with jquery draggable

Thanks for reporting this issue. This is indeed a bug. I'll have to take a look.

Here's a demo that demonstrates the problem a bit more clearly: https://codepen.io/desandro/pen/2abd0855b90c726e537c3923ec1b011e

I'm also facing the same issue in one of my project and the same case is also not working on the official website 's demo too
