A WebWorker declared in a dependency is not correctly bundled

[andsouto]

Command

build

Description

If a library that uses a Web Worker is used, the angular bundle generation is not including the worker file.

I made a mimimal reproduction case here: https://github.com/andsouto/angular-webworker-example

That project just imports in main.component.ts the next function from a dependency:

export function launchWorker() {
    console.warn('Example of creating a webworker in a dependency');
    const worker = new Worker(new URL('./x.worker', import.meta.url), {type: 'module'});
    worker.postMessage('foo');
}

If that code is included in the app itself it works as expected but when it is declared in a dependency it fails.

Afaik, in the dev server is not working because vite does not support this yet. More info including workarounds in this issue: https://github.com/vitejs/vite/issues/11672

But my main concern here is the production build because I suspect that is a problem in the angular build system itself and I wasn't able to find any workaround for this.
