Mojang did make an attempt to fix this. This bug is less apparent in this pre-release, therefore instead of being in a shaky boat inside of a glitched unloaded chunk as it seems like in the older releases, it just teleports me right back to the original gateway because it sets the player on top of the portal (instead of setting the player to the side as it usually does when not riding an entity).

Also, with a couple of attempts, I am still able to get into the weird shaky boat situation. Not in the first try however.
