MicrosoftEdge
[Problem/Bug]: FluentUI ComboBox/Select don't accept selected option in WinUI WebView2
What happened?
Original reports:
- https://github.com/microsoft/fluentui-blazor/issues/1741
- https://github.com/dotnet/maui/issues/22297
But the bug seems specific to WinUI WebView2 (doesn't repro on WPF WebView2).
Details: The FluentUI ComboBox (which internally uses an HTML <input> + some other HTML UI) doesn't accept selection in the WinUI WebView2. It works in regular Edge (just browsing the web), and it works in WPF WebView2.
Importance

Repro steps

<WebView2 Source="https://learn.microsoft.com/en-us/fluent-ui/web-components/components/combobox?pivots=typescript"></WebView2> - Run the app
- Scroll down to the bottom of the page and in the Example section make sure the Result tab is enabled, and in the dropdowns you see try to pick a 'graphics card' option. But it won't let you
If you try the same repro in a WPF WebView2 app it works fine (the graphics card is selected). And if you browser in regular Edge browser to https://learn.microsoft.com/en-us/fluent-ui/web-components/components/combobox?pivots=typescript then it also works fine.
