Cannot read properties of undefined in HtmlApp.ts

Trying to reproduce this. So far, the only context I can find is when an app is unregistered while being mounted. Example:

os.unregisterApp('test');
os.registerApp('test', thisBot);

const App = () => {
    os.unregisterApp('test')
    return (
        <button onClick={() => os.toast("clicked")}>
            click me
        </button>
    )
}

os.compileApp('test', <App />);
