Export builds don't seem to function properly in v8 for android or web

[randomdevpete]

Once I get an exported build running, I'm hitting all kinds of script errors. The build runs fine if I'm just using Godot nodes but as soon as I've attached a .ts script to a node I start getting problems. Specifically there is something wrong with get/set accessors so I'm unable to write to any properties on a node.

A very simple demonstration is to create a test scene with a sprite, then try to create a timer using this.get_tree().create_timer(1), and now try to connect to the timeout signal. I get an error that the timeout signal does not exist.

Alternately if I try to create the Timer node manually then set its properties and add it to the scene, I get an error that the properties have no set accessor.

Either example works fine just running the project directly in Godot, just the exported builds do not work.

(The same project using the qjs editor I'm able to export and run fine, so it's certainly an issue with the v8 editor and/or export templates)

Please provide a reproduction project. I understand setting these up can be time consuming, if you don't want to spend too long on this then this is probably a decent use case for an LLM/agent to put together for you.

In fact I already made one to isolate the issue, it was just on my other laptop at the time of posting the ticket. Apologies for not including it originally:

It's set up so if you export the web project to www/public/index.html then the following will run the browser (with HTTPS and cross original isolation already configured) using Vite dev server:

cd www
npm i
npm run dev

I'm quite sure it would have taken me far longer to wrangle an LLM to produce this :) To be honest I'm fairly sceptical how well an LLM would even handle GodotJS at all, since there are not exactly an abundance of code examples to draw from of Godot apps written in TS...
