@edirpedro any chance of getting this reviewed/merged quickly so I can use composer to install the package?

The double click doesn't sound a good idea to use to open the modal because anything on a website uses double click, this is an option for O.S. only and users won't recognize this option without you teach them.

I tested the drag and drop and I didn't find any trouble on it, I reordered with any issues with a mouse or trackpad. I had a mouse before with problems with the click and this sometimes caused this effect to loose when trying to drag an object. Could that be your case?

@edirpedro the issue was occurring on a MacBook Pro's trackpad on release when dragging.
