how weird it would have to work ... You can look at any of these three.js projects if these projects work, I mean they load even if it is slow, I would also have to load this project since they use the same web technology.
also if you want to get more doubts try the project directly from here you can download it and open it with Godot 3.1.2 or with godot 3.2.3 beta
