I really don’t like this. It took me several attempts to figure out what was going on.

And even after I had finally figured it out, it still felt more like a rendering glitch than good UX.

If I struggled then I really can’t see this working for non-technical folk.

Worse yet, because people wouldn’t expect this behaviour coupled with the fact that scrolling shouldn’t have any changes to the website state, you’ll likely see people constantly making accidental changes to the ordering of the list.
