this is working as intended
see https://tanstack.com/start/latest/docs/framework/react/selective-ssr#fallback-rendering

oh, i see. thanks!
but is there really a point in displaying a pending component even when the loader is not configured?
schiller-manuel commentedon Sep 11, 2025
you could still want a server fallback to prevent layout shift

encountered this quirk too, very counter-intuitive default 😭
