Alert popup not displaying when dismissing modal page on iOS/MacOS

[Kbperri]

Description

If I open a modal page, in this case a sign in page from the ArcGIS Maps SDK, and then dismiss the page, popups don't work immediately. If I add a delay after the sign in page is closed, the popup will be shown.

Steps to Reproduce

1. Open the iOSBackgroundIssue solution
2. Run the app
3. Click on the "Click me" button
4. Click "Continue" on the sign in popup
5. Click "Cancel" on the sign in page
6. Notice that none of the alerts are shown.

Hi! @LogishaSelvarajSF4525 and @Kbperri My friend copilot with our issue-resolver agent, came up with this solution #32872. I’ve tested it, and it works correctly in a sample project created purely in MAUI. Could you please check whether it also works in your specific case?

Thanks!
