bug: Alert button handlers are executed outside the angular zone in certain cases

[Airdevelopments]

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

v7.x

Current Behavior

Button handlers of alerts seem to be executed outside the Angular Zone (at least in certain cases).

Strangely enough, when the page is loaded with device emulation, the issue does not seem to appear:

This is causing issues when calling angular related functions like trying to start navigation, since these must be called inside the angular zone.

Expected Behavior

We would always expect a button handler to run inside the Angular Zone.

Steps to Reproduce

1. Clone provided reproduction repository
2. npm run start
3. Open browser dev tools
4. Make sure device emulation is not enabled
5. Click the button on Tab 1
6. Click the button in the alert
7. Watch the dev console output

Thank you for the issue. I'm able to replicate this, but I need to dig deeper into why it's happening.

It looks like the issue is around how we've set up the callback to run in Angular Standalone, specifically. Normally we use a util that ensures the callbacks are run in the Angular zone, but that may not be getting used in a standalone app. I'll raise this with the team so we can take a closer look 👀
