When riding passenger on a flying mount over an area that has no land below, how does the game handles it if the person driving the chocobo gets disconnected?

Does the game let you fall to your death to resurrect at your respawn Aetheryte? Does the game crash? Do you fall and get stuck? Are you automatically placed on a flying mount? Are you instantly teleported to an Aetheryte without death?

I'm curious what happens since the game normally prevents you from going out of bounds unless flying and prevents you from dismounting unless on solid ground
