Monaco Editor Playground Code

const tsCode = `
// Typescript

const f = async function () {
    alert('hi');
};
`;

// Hover on each property to see its docs!
const myEditor1 = monaco.editor.create(document.getElementById("container1"), {
	value: tsCode,
	language: 'typescript',
	automaticLayout: false,
});

Reproduction Steps

Just loading the provided playground URL in the browser should be enough.

Actual (Problematic) Behavior

"The browser fails to load the workerMain.js file because it attempts to fetch it from 'https://microsoft.github.io/node_modules/monaco-editor/min/vs/base/worker/workerMain.js#editorWorkerService' instead of the correct URL 'https://microsoft.github.io/monaco-editor/node_modules/monaco-editor/min/vs/base/worker/workerMain.js#editorWorkerService'.
In other words, the URL needs to be absolute rather than relative.
Check the browser console for more info."

Expected Behavior

The resource should be fetched.

Additional Context

This bug is specific to the playground.

Can also confirm that this happens in our application when upgraded from 0.48.0 to 0.52.0.

Uncaught NetworkError: Failed to execute 'importScripts' on 'WorkerGlobalScope': The script at 'http://localhost:8080/assets/monaco/vs/base/worker/workerMain.js#editorWorkerService' failed to load.

Where the url should point to http://localhost:8080/iaf-example/iaf/gui/assets/monaco/vs/base/worker/workerMain.js instead of http://localhost:8080/assets/monaco/vs/base/worker/workerMain.js

The same error happens even when you visit the home of the Monaco project https://microsoft.github.io/monaco-editor/

Just open https://microsoft.github.io/monaco-editor/ and check developer console.

Many included examples have the same issue.
