In the myths, the king of Alfheim was a god named Freyr, not Elsa. That might have been a Marvel-specific detail, or perhaps foreshadowing. Harry truly had no way of knowing whether Elsa was really a queen.

Perhaps because Odin was nominally still alive, and because the Light Elves believed Heimdall was constantly watching the Nine Realms, they had realized something was wrong but had no intention of defying Odin's will.
