why does onAuthStateChanged not fire when you signup via email/password? is this because the session is null until the email is verified? But isn't the whole point of an observer like this to observe and alert listeners about every auth state change? is signing up not considered a change in the state of the auth? this behavior is quite different from firebase auth's onAuthStateChanged observer, idk if it's a bug or some explicit design decision but it's counter-intuitive. This could very well be considered a side effect of this issue: https://github.com/supabase/supabase/issues/2715
