pub(crate) fn get_load_state_rc(&self) -> RcSignal<RouterLoadState> {
        self.load_state.clone() // TODO Better approach than cloning here?
    }
Gets the load state of the router. You'll still need to call `.get()`
after this (this just returns a `RcSignal` to derive other state from in
a `create_memo` or the like).

This is designed for internal use only. End users should get a reference
with `.get_load_state()`.
