[praveenkumarkarunanithi]

Description

On the Windows platform, the WebView's OnNavigated event returns WebNavigationResult.Failure for URLs containing non-Western characters, even though the webpage is properly loaded. It is working fine in other platforms.

Steps to Reproduce

1. Run the attached simple sample:
   WebviewIssueSample.zip
   The sample uses a WebView with a URL containing encoded non-Western characters.
2. Click "Load URL" to load the WebView: This will trigger the navigation to the specified URL.
3. Observe the label: The label shows "Failed to navigate" because the WebNavigationResult is coming as Failure even though the webpage is properly rendered on the Windows platform.

This issue occurs due to a native WebView2 limitation on Windows. The OnNavigated event in MAUI returns WebNavigationResult.Failure for URLs containing non-Western characters, even though the webpage is properly loaded. This behavior has been confirmed as a WebView2 issue and has been reported separately in the WinUI repository.
For reference, see the reported WebView2 issue here: GitHub Issue #10339.
