-    This can be considered a *BREAKING CHANGE* in very specific cases:
-    Typically, this means you are relying on implicit type inference, such as `let webview: _ = WebviewWindow.as_ref()`.
-    To resolve this, you should explicitly specify the type, for example `let webview: &Window<R> = WebviewWindow.as_ref()`
-    or `let webview: _ = AsRef::<Webview<R>>::as_ref(&WebviewWindow)`.
