Wormhole glitch 2.0

About a month ago I experienced a strange bug where my elytra was glitching out and mobs froze and I was kicked from the server again and again and I was teleported to random caves. I made a report and I didn't have video evidence back then and a person at mojang said when I have proof to make a new report so here it is. I will copy paste the original report here as well.
All I did was take a firework out to fly to my friends base the firework was duration 1 but the firework did not stop it kept going for 30 seconds before i landed but I stayed in the flying position and when I tried to jump I stayed in the flying position and jumped like I had jump boost and I randomly tp'd to a cave and lost all my items and was kicked from the server and this repeated multiple time at first I thought it was lag but I have experienced this before and it can be used to walk through walls in survival minecraft and this was what people used for the wormhole exploit and this could potentially be used to do the wormhole glitch again if it ends up in the wrong hands.
