Dynamic title fails to set on 1st client-side navigation: `loaderData` undefined

So here's a usual article/post route setup:
export const Route = createFileRoute('/article/$id')({
    loader: async ({ params, context }) => {
        console.log('Loader running for article:', params.id);
        const data = await context.queryClient.ensureQueryData(
            articleQy(params.id),
        );
        console.log('Loader data:', data);
        return data;
    },
    
    head: ({ loaderData }) => {
        console.log('Head function called with loaderData:', loaderData);
        return {
            meta: [{ title: pageTitle(loaderData?.title ?? 'Article title n/a') }],
        };
    },
    
    component: ArticleDetailPage,
});


When I first navigate to an article, from the article list page, the title fails to show; but if I revisit that same article for the second time, the title is set correctly.

Indeed, the 
loader
 function prints out valid data, but the 
head
 function prints that its loaderData is undefined!

Is this a known issue, or am I missing something?
