Hey @jjhuff 👋

I've just checked the snippet, and yes, you are right, the issue exists. But I also tried to reproduce it in the monaco-playground to be sure if the issue related to the react wrapper or to the original package. And it seems the issue is related to the original package. To reproduce it try the code below in the above-mentioned playground.

const model1 = monaco.editor.createModel(`
const foo=1;
`, 'javascript', 'root/js/file1.js');

const model2 = monaco.editor.createModel(`
const foo=2;
const bar=3;
`, 'javascript', 'root/js/file2.js');

const editor = monaco.editor.create(document.getElementById('container'), {
    model: model1,
});

setTimeout(() => {
  editor.setModel(model2);
}, 500);

setTimeout(() => {
  editor.setModel(model1);
}, 1000);

Awesome, thanks for the playground snippet! I filed over on the main project.
