Items bounce when dragging

[jpintog]

Hi there!
this is my issue:
I have a nested list of multiple items, and the items have some drop conditions, some of them have predefined children and the user can not drop more items inside (but is possible in the children), the thing is when I drag an item above the drop zone of other item (where the item I'm dragging can not be dropped) the items other items start bouncing.

I solved it duplicating the list and setting it without the drag&drop directives for the items with predefined children, but it would be better if setting the dndDropzone like [dndDropzone]="'none'" was enough

thanks!

Can you provide a small reproduction stackblitz or have a repo that I can check out?

Here is a template for stackblitz: https://stackblitz.com/edit/ngx-drag-drop-issue-template

Items should no longer "bounce" when being dragged.
