Disallow editing invariant properties seems not to work with v15

Questions
1

I am running a fresh install of Umbraco v15.4.0 with Visual Studio. It seems that AllowEditInvariantFromNonDefault: false in appsettings.json has no effect on editing properties that do not vary by culture. In fact I can change their values from all languages, but as I understood this should only be possible from within the default language?! Is this a bug?

Additional note: Also on the Live-Website, this setting does not seem to work. When I try to edit a shared property in a language other than the default one, I can do it. Although the “shared” label shows up, I would expect that editing the property is not possible at all.

It SOUNDS like a bug. Can you create an issue for it?
