Reproduction of Vite problems including eventemitter3 as a transitive dependency

Vite SSR eventemitter3 Transitive Dependency Reproduction

To run

1. pnpm i
2. pnpm dev
3. Open the browser

Note that you can reproduce this with yarn as well if you prefer.

It appears that when included as a transitive dependency eventemitter3 is not prebundled, and since it's a CommonJS package this causes problems. In the reproduction repository case it's being included through the @solana/wallet-adapter-base package.

Using yarn we can add eventemitter3 to optimizeDeps.include, but with pnpm it's nested in some other directories, so that doesn't work and I get a "Failed to resolve force included dependency" error. I also tried "@solana/wallet-adapter-base > eventemitter3" but that didn't seem to do anything.

The eventemitter3 package does some unusual stuff at the end when it exposes the module:

if ('undefined' !== typeof module) {
  module.exports = EventEmitter;
}

And then when it actually runs, since it hasn't been converted to ESM module is undefined and it can't do anything.
