[dev-v5] `FluentToast` does not respect `DefaultValues`

[MarvinKlein1508]

🐛 Bug Report

I want to setup my toasts globally to alway be on the TopEnd are dismissible and inverted by default. So I tried to use the built in default values feature to specify these values. However they are being ignored.

As a workaround you can create a custom extension method which always sets this values to the FluentOptions but I believe it would be great if this was supported out of the box.

💻 Repro or Code Sample

I defined this two default values in Program.cs

options.DefaultValues.For<FluentToast>().Set(p => p.IsDismissable, true);
options.DefaultValues.For<FluentToast>().Set(p => p.Position, ToastPosition.TopEnd);

🤔 Expected Behavior

I expect the default values to be respected

😯 Current Behavior

They will be ignored completely.
