const myEditor = monaco.editor.create(document.getElementById("container"), {
	value,
	language: "python",
	automaticLayout: true,
	fontSize: 10

let toggler = true;

setInterval(() => {
	myEditor.updateOptions({ fontSize: toggler ? 30 : 10 });
	toggler = !toggler
}, 2000)

Additional Context

No response

Start with the linked Monaco Editor Playground and reproduce the issue using the shown monaco.editor.create setup and updateOptions({ fontSize }) calls. Trace the sticky scroll widget's response to the font-size change; done means its text uses the updated editor font size while it remains visible.
