`--target web` causes `Error: not implemented... yet...`

🐛 Bug description

I've got a typescript module written on top of wasm bindings from rust. With wasm-pack build --target bundler I can run tests and everything works correctly. But if I change target to web and add await init(); on top of my module I get errors

 FAIL  test/types.test.ts [ test/types.test.ts ]
TypeError: fetch failed
 ❯ __wbg_init pkg/cooklang_wasm.js:577:51

🤔 Expected Behavior

My tests pass.

👟 Steps to reproduce

Use --target web, add import init from "pkg/some_package.js"; await init(); and run vitest importing the module.
