There is a very big mistake in this new version because I want it fixed by a elytra you can transfer blocks minecraft and can walk only one block up and also you can go under the blocks

partially blocked in 18w44a - player can only fly under transparent blocks now

HOW? How does this "work as intended"??
This is a thing since 1.9 and its ridiculous... Every player can basically strip mine in 1x1x1 tunnels if they have an elytra, which essentially doubles the efficiency of mining. Its so easy. Unbelievable.
If a player is {FallFlying:0b} then its hitbox should ALWAYS be 2 blocks high. Same applies for swimming!
Is this confirmed as WAI by Mojang?
