Monaco Editor Playground Code

const value = /* set from `myEditor.getModel()`: */ `function hello() {
	alert('Hello world!');
}`;

// Hover on each property to see its docs!
const myEditor = monaco.editor.create(document.getElementById("container"), {
	value,
	theme: 'vs',
	language: "javascript",
	automaticLayout: true,
});

const value2 = /* set from `myEditor.getModel()`: */ `function hello() {
	alert('Hello world!');
}`;

// Hover on each property to see its docs!
const myEditor2 = monaco.editor.create(document.getElementById("container2"), {
	value,
	language: "javascript",
	theme: 'vs-dark',
	automaticLayout: true,
});

Reproduction Steps

1、Create an editor and set the theme to 'vs' 2、Create a second editor with the theme 'vs-dark'

Actual (Problematic) Behavior

The themes of the two Monaco editors are the same

Expected Behavior

Each Monaco editor should apply its own theme
