@Environment doesn't work on StaticLayout

[mfreiwald]

I try to use the ThemeSwitch on my Home-Page. The implementation is like this:

struct ThemeSwitcher: HTML {
   @Environment(\.themes) var themes
   var body: some HTML {
        ForEach(themes) { theme in
            Button(theme.id) {
	        SwitchTheme(theme.id)
	    }
       }
   }
}

But using this in my Home-Page doesn't work, the Theme-Array in @Environment(\.theme) is empty.

struct Home: StaticLayout {
    var title = "Home"
    var body: some HTML {
        ThemeSwitcher() // No buttons visible because themes is empty
    }
}

But using the ThemeSwitch in the Layout works:

struct MyLayout: Layout {
    var id: String = "my-layout"

    @Environment(\.siteConfiguration) private var config

    var body: some HTML {
        HTMLDocument {
            HTMLHead(for: page, with: config)
            HTMLBody {
                Group(page.body)
                ThemeSwitcher() // theme buttons visible
            }

        }
    }
}
