Description
What happened?
We have a .NET 8 console application that ultimately spawns a WebView2 Control within a WinForm
We've recently set <InvariantGlobalization>true</InvariantGlobalization> in our .csproj to deal with System.Text JSON deserialization issues,
Since this has been released we've been seeing the following in our logs
System.Globalization.CultureNotFoundException
Only the invariant culture is supported in globalization-invariant mode. See https://aka.ms/GlobalizationInvariantMode for more information. (Parameter 'culture')
3081 (0x0c09) is an invalid culture identifier.
Stack trace:
System.Globalization.CultureInfo.GetCultureInfo(Int32 culture):92
System.Windows.Forms.InputLanguage.get_LanguageTag():203
System.Windows.Forms.InputLanguageChangedEventArgs..ctor(InputLanguage inputLanguage, Byte charSet):23
System.Windows.Forms.InputLanguage.CreateInputLanguageChangedEventArgs(Message m):16

Microsoft.Web.WebView2.WinForms.WebView2.WndProc(Message& m):58
System.Windows.Forms.NativeWindow.Callback(HWND hWnd, MessageId msg, WPARAM wparam, LPARAM lparam):42
We aren't explicitly attempting to set any culture info on the WebView2 control
Can someone confirm if this a supported configuration?
