Monaco Editor Playground Code

monaco.editor.create(document.getElementById('container'), {
    value: "function hello() {\n\talert('Hello world!');\n}",
    language: 'javascript'
});

setTimeout(() => {
    monaco.languages.typescript.javascriptDefaults.setCompilerOptions({
        target: monaco.languages.typescript.ScriptTarget.Latest
    });
}, 3000);

Have a look at the network tab and notice how after 3 seconds, workerMain.js and tsWorker.js are unnecessarily fetched again.

Observed in Monaco v0.32.1
