Can WebAssembly (Wasm) be supported to run in environments without DOM, such as in WeChat Mini Programs?

Operating System

• Windows
• macOS
• Linux
• FreeBSD
• OpenBSD
• Android
• iOS
• Nintendo Switch
• PlayStation 5
• Xbox
• Web Browsers

What feature would you like to be added?

Currently, I'm attempting to run a game using Wasm in WeChat or Douyin Mini Programs. However, due to the absence of DOM in this environment, it results in the following error message.

I found that the issue lies in "ebiten\internal\ui\ui_js.go", where using "js.Global().Get("window")" results in obtaining undefined. Could you provide support that is compatible with such environments?

Why is this needed?

Ebitengine uses a canvas so cannot support an environment where this doesn't exist.
