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,
	language: "javascript",
	automaticLayout: true,
});

myEditor.onDidChangeConfiguration((e) => {
    alert("Config changed!")
});

Reproduction Steps

1. Add handler for onDidChangeConfiguration
2. In Monaco Editor, click Ctrl + M to change tab focus mode
3. Observe that an event is not raised for onDidChangeConfiguration, but the tab focus mode is changed in the editor

Actual (Problematic) Behavior

The handler for onDidChangeConfiguration is not called.

Expected Behavior

The handler for onDidChangeConfiguration should be called

Additional Context

This issue seems to have originated from 0.36.0. May be related to this bug:

https://github.com/microsoft/monaco-editor/issues/1493

Start with the Monaco Editor Playground reproduction and the IStandaloneCodeEditor.onDidChangeConfiguration entry point. Trace how changing tabFocusMode through Ctrl+M updates the editor configuration, then verify that the configuration-change handler fires for that change. Done means the reported playground scenario raises the event without breaking other configuration changes.
