Issue when activating clone mode in nested lists

[minedun6]

The problem is that I have a requirement to have a handler to move items and a handler to copy/clone elements inside a nested structure. The first requirement is fine, problem is when I'm trying to do the cloning part,

Codepen example

Here's the scenario,

• Step 1
  When I move "Video.mp4" inside "Folder 2" , what I am expecting is that node is cloned
  inside the said "Folder 2". The problem is that it gets moved instead of cloned.
• Step 2
  When I move "Video.mp4" back from under "Folder 2" to the same level of "Folder 2", this time, it gets cloned properly.

So I'd like if someone could explain to me where I'm going wrong with this or is it actually a bug ?

How strange. That looks like a bug to me, unless there is some workaround that we don't know of.

Thank you
