Can't bind to Uri-path for Source property

[duck-dev]

Describe the bug
I can't bind to a property of type Uri (not even Uri?) for the Source property of a StyleInclude in this case. I get faced with this error upon building the application:

[XAMLIL] Unable to find suitable setter or adder for property Source of type Avalonia.Markup.Xaml:Avalonia.Markup.Xaml.Styling.StyleInclude for argument Avalonia.Markup:Avalonia.Data.Binding, available setter parameter lists are:
System.Uri Line 16, position 23.

I hope I'm not missing something too obvious, which is not unlikely to happen, considering my current state of concentration due to specific reasons, but I'm pretty sure this looks plausible. I'm not able to see where the issue lies.

The reason why I'm opening an issue for this, is that it might not look like expected behaviour at once and is possible to be an internal issue. It would also automatically be a proposal for a "feature" if it's not intended to bind for Uri sources.
I thoroughly searched through previous issues and the internet in general, which didn't help me much.

To Reproduce
App.axaml:

<Application.Styles>
    <StyleInclude Source="{Binding SomeSource}"/>
</Application.Styles>

App.axaml.cs:

private Uri SomeSource // Same thing with nullable type (Uri?)
{
    get => _someSource; 
    set => this.SetAndRaise(_someSourceProperty, ref _someSource, value);
}

Expected behavior
It should bind correctly and not throw this error.

Source binding isn't supported, just like it isn't in wpf/uwp.

@maxkatz6 Thank you very much for your answer!

That's what I supposed. Is there a specific reason for that, which is not necessarily bound to difficulties in implementation or is exactly that the reason, which I doubt if it isn't supported in WPF and UWP either?

And while we're at it, what would you propose as a better way to have a path that may change at runtime? A dynamic resource for example?

Simply remove this and add new StyleInclude from the styles collection. It will work.

Oh yes, that definitely makes sense. Just removing this entry from Application.Styles and adding a new one is very acceptable.

Thank you a lot!
