When going through an end gateway from the main island to the outer ones, the player gets stuck in a block which can lead to falling into the void.

When going through an end gateway from the main island to the outer islands, instead of just landing safely on the other side, the player gets stuck inside of the block that they land on. Sometimes, if the spawn is right beside a drop into the void, they will fall into the void and die.

 

Steps to reproduce:

1) Kill the dragon in the end in 1.14.1

2) Go through an end gateway
