DisplayAlert() does not reflect Windows theme changes

[King-Taz]

Description

DisplayAlert() will not immediately reflect Win11 theme changes. User must close/reopen app for theme changes to be reflected.

Steps to Reproduce

Create Maui app with button that calls a method containing

DisplayAlert("Theme Change", "Test message", "Close");

With the app running, change theme light/dark and see colors do not change. Restart app and verify colors have now been changed.
