Eerie Mojang Office Party Dupe/Out Of Bounds

I was messing around in the new Mojang Office Party when I came across a dupe + out of bounds glitch. I wanted to find a way to keep the elytra outside of the "Idea Vault" minigame. So I started to fly around until I slipped through a respawn barrier  at the first elytra ring, allowing me to finish with an incredible time and place 1st on the leader boards. I them wondered if I could use this to have the elytra at the start of the race. When landing on the warp back to the top, and flying around the goal triggers, you can use your elytra to fly over the barriers and die in the void. This then would cause the inventory to refresh itself every frame while not airborne meaning you can drop as many "Office key", "Seed boost", "Jump Boost" "Dev Hat" "Eerie Soup", "Mystery potion" as you please. 

 

I've attached a video running through what I did and how to replicate the exploit here: https://youtu.be/Ry0QY-yMPyk
