fix: FluentMenu broken in published release build

🐛 Bug Report

I have a basic FluentMenu.

On local development build everything works great. On a published release build clicking the FluentMenuItem causes an exception. There are no other warnings or exceptions visible in dev tools.

That’s all the info I have at this point. I can try to come up with minimal repro in few days.

This is added for FluentSwitch in version 2.1 which will be released in the coming days

Ok, applying the same trick with the attribute on the DesignToken constructor resolved the error in the minimal repo. Please test again with this package
