In previous versions of mcpe after falling beyond bedrock you would either land on an invisible platform or die from falling from a dangerous height. Now you fall endlessly and the only way to get out is to either fly up until you reach the top (which may take forever depending on how fall you fell) or you switch to survival to kill yourself and respawn in the world.

Confirmed. After re-join you get teleported up a bit, like almost same depth as with the invisible platform once
