Component based gamemodes are not working consistently

[unickorn]

I wanted to allow people to toggle flight in a world where the default gamemode is Adventure.

Since there is no way of allowing flight like on other server software, I went with a custom gamemode I called GameModeFlying:

type GameModeFlying struct {
	world.GameModeAdventure
}

func (GameModeFlying) AllowsFlying() bool {
	return true
}

Switching to this gamemode however simply keeps everything entirely same. However, when I return false for AllowsInteraction, flight works fine.
