Compile error with refactored routes

Describe the bug Trying to refactor some <Route>s out into a transparent component, as shown in the book. Hitting compilation errors:

the trait RenderHtml is not implemented for View<NestedRoute<Signal<String>, (), (), ...>>
no method named children found for struct RoutePropsBuilder in the current scope

Leptos Dependencies

[workspace.dependencies]
leptos = { version = "0.7.0-rc1", features = ["ssr", "hydrate", "nightly"] }
leptos_meta = { version = "0.7.0-rc1" }
leptos_router = { version = "0.7.0-rc1", features = ["nightly"] }
leptos_axum = { version = "0.7.0-rc1" }

To Reproduce

start with example of https://book.leptos.dev/router/17_nested_routing.html#refactoring-route-definitions
make minimal porting changes for 0.7 (hopefully!)
cargo build

Expected behavior Should compile.

Screenshots Actual code (test.rs)

use leptos::prelude::*;
use leptos_router::components::*;

#[component]
fn App() -> impl IntoView {
  view! {
    <Router>
      <Routes fallback=|| "Page not found.".into_view()>

          <ContactInfoRoutes/>
          <Route path="" view=|| view! {
            <p>"Select a contact to view more info."</p>
