System.Windows.Input.ModifierKeysConverter.GetModifierKeys - NotSupportedException on Preview6

[Symbai]

• .NET Core Version: 3.0 Preview6
• Windows version: 10
• Does the bug reproduce also in WPF for .NET Framework 4.8?: No
• Does the bug reproduce also in WPF for .NET Core Preview 4: No

Problem description:

<MenuItem Command="ApplicationCommands.Undo" /> crashes with System.NotSupportedException: Unknown ModifierKeys "STRG". While STRG is the German translation of CTRL. Switching back to Preview4 and everything works fine.

Please note that ApplicationCommands.Copy and others, I assume all that uses CTRL, crashes too.

Actual behavior:

"   at System.Windows.Markup.XamlReader.RewrapException(Exception e, IXamlLineInfo lineInfo, Uri baseUri)"

Minimal repo:
You may need to run this with a German Windows version.

This was already fixed by #919 - you can use daily builds as described here or change your resource language to en-US (CultureInfo.CurrentUICulture = CultureInfo.GetCultureInfo("en-US");) until preview 7 is released.
