[feature] Possibility to create the clone manually (and prevent cloning if not necessary)

Hi,

I have web components that I want to sort. But my web components expect a few parameters in constructors. But when I drag one, the element is cloned so I have an error due to missing constructor parameters. By the way, could we prevent the cloning of the element ?

It would be useful if we could create the clone on our own (so that we could possibly pass some additional parameters to the constructor)
