[Android] Loaded event not triggered when navigating back to a previous page

### Description

I'm encountering an issue where the Loaded event is triggered as expected the first time the page appears. However, after navigating to another page and then returning, the Loaded event does not fire again. This behavior occurs only on the Android platform—it works correctly on Windows, macOS, and iOS.

### Steps to Reproduce

1. Run the attached sample.
2. Note the loaded event of the main page is triggered as expected the first time
3. Click on the "Click to navigate new page" button to navigate another page.
4. Now click on "Click to navigate main page" button to navigate main page.
5. Note the loaded event is not triggered after navigated to main page.
