So I was playing in spawn with my elytra flying around when I decided to jump off of the trading house. When I flew over the pressure plate in the arena, I started flying up instead of gliding down. Turns out with an elytra and some skilled flying, you can preform the super jump glitch again. I have told Tezzer, Celexya, And Baron this, andI have demonstrated the glitch to Danny. After some testing I did, you can’t get on top of the arena, and it requires an elytra to preform. The glitch isn’t really game-breaking, as in you don’t really gain any advantages with it, but I imagine it would still need to be fixed. Thanks for your time.

Ive just been informed by cactus that this isn't a glitch, but using the delay of the effect and not much can be done.
