WebView2 not handling DOM events properly

[Foda]

Describe the bug

Starting from WindowsAppSDK 1.4.240211001, DOM events fired inside WebView2 are not handled properly, making the use of custom select boxes (for instance) impossible.

Copied from dotnet/maui#22697 as this issue is affecting customers of MAUI.

Note: this does NOT happen in the WPF/WinForms version of Webview2 -- it is an issue specifically w/ WinAppSDK

Steps to reproduce the bug

1. Just create a new app and add the following XAML:
   <WebView2 x:Name="webView" Source="https://google.com"/>

2. Click on the app selector icon.

3. Click on any link to be redirected to any Google app.

4. The menu closes and the navigation is not done.

Expected behavior

The navigation to the selected Google app should have been done.
