Async imports from workers don't work: 'Cannot find module'

[mischnic]

🐛 bug report

🤔 Expected Behavior

The entry asset of the async bundle should be registered into parcelRequire

😯 Current Behavior

• Uncaught (in promise) Error: Cannot find module '6CLGt'

💁 Possible Solution

I think isAssetReferencedByDependant is wrong? There is no parcelRequire.register() in the async bundle

💻 Code Sample

parcel build index.html

<script src="index.js"></script>

// index.js
new Worker("./worker.js");

// worker.js
import("./async.js").then((v) => console.log("worker: async=", v));

// async.js
export const async = "async!";
