component render running before "beforeLoad"

root.tsx

export const Route = createRootRouteWithContext<{
    auth: {
        session: Session;
        user: UserWithAnonymous;
    } | null;
}>()({
   beforeLoad: async () => {
        const { data } = await authClient.getSession();
        return { auth: data };
    },
    loader: ({ context }) => {
        return { user: context.auth?.user };
    },
    component: () => (
        <RootDocument>
            <Outlet />
            <TanStackRouterDevtools position="bottom-right" />
        </RootDocument>
    ),
});

function RootDocument({ children }: { children: React.ReactNode }) {
    return (
        <html lang="en">
            <head>
                <HeadContent />
            </head>
            <body className="bg-secondary">
                <AuthLayer>{children}</AuthLayer>
                <Scripts />
            </body>
        </html>
    );
}


auth-layer.tsx

```tsx
import { authClient } from "@/lib/auth/client";
import { getRouteApi, useRouter } from "@tanstack/react-router";
import { Loader } from "lucide-react";
import type React from "react";
import { useEffect } from "react";

export default function AuthLayer({
children,
}: {
children: React.ReactNode;
}) {
const routeApi = getRouteApi("root__");
const { user } = routeApi.useLoaderData();

const router = useRouter();

useEffect(() => {
if (!user || !user.isAnonymous) {
(async () => {
await authClient.signIn.anonymous();
await router.invalidate();
})();
}
}, [user]);

if (user) {
return <>{children}</>;
}

return (
<div className="flex min-h-screen items-center justify-center">
<Loader className="size-4 animate-spin" />
</div>
);
}
```

the anonymous signin call is being made before getSession
