wasm-bindgen 0.2.95 leads to webpack build errors for --target bundler

[Jeroendevr]

Describe the Bug

Upgrade from 0.2.93 to 0.2.95 breaks some webpack builds

Steps to Reproduce

The following is a result of following the hello-wasm tutorial

1. Compile the following code
   See https://github.com/Jeroendevr/hello-wasm/tree/bug-0.2.95 for full repo

lib.rs

use wasm_bindgen::prelude::*;

#[wasm_bindgen]
extern {
    pub fn alert(s: &str);
}

#[wasm_bindgen]
pub fn greet(name: &str) {
    alert(&format!("Hello, {}!", name));
}

cargo.toml

[package]
name = "hello-wasm"
version = "0.1.0"
edition = "2021"

[lib]
crate-type = ["cdylib"]

[dependencies]
wasm-bindgen = "=0.2.95"

package.json

{
  "name": "hello-wasm",
  "version": "1.0.0",
  "main": "index.js",
  "author": "",
  "license": "ISC",
  "description": "",
  "scripts": {
    "build": "webpack --config webpack.config.js",
    "serve": "webpack serve --config webpack.config.js --open"
  },
  "dependencies": {
    "hello-wasm": "file:../pkg"
  },
  "devDependencies": {
    "copy-webpack-plugin": "^11.0.0",
    "webpack": "^5.96.1",
    "webpack-cli": "^5.1.4",
    "webpack-dev-server": "^4.15.2"
  }
}

3. Run terminal

wasm-pack build --target bundler
cd site
npm run build

6. See error

Expected Behavior

Succesfull build and a webpage on localhost displaying an alert message

Actual Behavior

The following build error

❯ npm run build

> hello-wasm@1.0.0 build
> webpack --config webpack.config.js

Additional Context

This works on wasm-bindgen 0.2.93
I have no experience with wasm just following the tutorial. I tried to verify that I have taken all the correct steps.

I think this is a duplicate of #4211.

[Jeroendevr]

Yes I think as well, I'll close this. Thanks for pointing out, I missed that one.
