[SimonGolms]

Prerequisites

• I have read the Contributing Guidelines.
• I agree to follow the Code of Conduct.
• I have searched for existing issues that already report this problem, without success.

Ionic Framework Version

• v4.x
• v5.x
• v6.x
• Nightly

Current Behavior

Upgraded application use to ionic v6 and react v18 and followed the official upgrade guide to react v18:

// https://reactjs.org/blog/2022/03/08/react-18-upgrade-guide.html#updates-to-client-rendering-apis
// Before
import { render } from 'react-dom';
const container = document.getElementById('app');
render(<App tab="home" />, container);

// After
import { createRoot } from 'react-dom/client';
const container = document.getElementById('app');
const root = createRoot(container); // createRoot(container!) if you use TypeScript
root.render(<App tab="home" />);

After updating to client renderings, the <IonAlert /> component do not open/render anymore.

Expected Behavior

Expect <IonAlert /> component to open/render

Steps to Reproduce

Following the Stackblitz example:

1. Click the button Show Alert Hook to open the alert modal via useIonAlert -> Alert modal open
2. Click the button Show Alert Component to open the alert modal as a component -> Alert modal not open
3. Open the index.js file and switch the comments block to use ReactDOM.render()
4. Click the button Show Alert Component to open the alert modal as a component -> Alert modal open

Thanks for reporting this issue & providing a reproduction! I am seeing the same issue. We will track this as a bug. Will need to do some exploration into the React 18 changes on my end.

I just found out that the component <IonLoading /> is also affected! https://stackblitz.com/edit/react-1udk9j-pvesdl?file=main.js,index.js

Hello @SimonGolms can you test with this dev build and let me know if the problem persists?

6.1.7-dev.11653598324.17fa560b

The new behaviors for strict mode in development mode uncovered a flaw in our controller component that it could not be unmounted and re-mounted multiple times.

@sean-perkins I could not reproduce the problem in my local repo and the stackblitz examples - thanks!
