WebRTC is not working on HTML5 export of Godot 4.2 Dev

Godot version

4.2.dev

System information

Windows 10 - NVIDIA GeForce RTX 2080 SUPER [Version 531.29] - Godot 4.2.dev

Issue description

WebRTC is not working on HTML5 export of Godot 4.2 dev. In testing the Nakama-WebRTC demo project, I face a problem with Web export. Users get stuck in the connecting state.

Steps to reproduce

1- export the project in this link for HTML5. ( Test can be done by running the exported project locally or on a web host like itch.io.
2- configure a Nakama server with an SSL certificate and use port forwarding to secure the Nakama port
3- try to authenticate on the exported app.
4- create a room with one client and joint with another one.
5- It stucks in the connecting state.

Minimal reproduction project

NA (I didn't manipulate the original project except for port and server address)

Is this the same as #80022?

No, the previous one was related to HttpRequest this one is about making peer-to-peer connections using WebRTC.
The problem rises after authentication is done by HttpRequest.
The first user connects without a problem. But the other users who join the room are stuck in the connecting state.
I guess something goes wrong when add_peer wants to add the other users' players to the room.

I need some more time to investigate, but I strongly suspect this is a bug in my addon rather than Godot itself. On my Discord, another user has been having some trouble with the Godot 4 version of the addon - I was able to fix one of their bugs, but some still remain. I'll try to find some time this week to dig deeper into it.

Actually I made some more tests and it works properly in Chrome browser. But in Mozilla, joining a room stucks in the connecting state. I'm trying to understand what is wrong with Mozilla.
Thanks for your awesome project anyway. I'm looking forward new modifications of the project.

I can't seem to be able to reproduce using the webrtc_signaling demo, tested with both Chromium and Firefox
