Unable to drag elements with JS in Browser Interaction window

[dogbog]

I'm trying to write a simple page which has a user list where you can drag each name around to reorder them. I tried using some example code found on the web to see if this works, but nothing happens at all inside of OBS's browser interaction window. However, it works fine inside of a real browser and also works in OBS if you open the page as a browser dock by clicking View > Docks > Custom Browser Docks.... and putting in the path to that HTML file.

Here the code I'm using:
JSFiddle : draggable list

I'm using OBS v26.1.1. Is there a way to update chromium embedded framework so that this would work? Or maybe some other way of dragging elements around?

Anyone? It's strange that it works perfectly inside of a dock that probably uses the same chromium framework that the interaction window uses.
