Launched by Ender Dragon around 700 blocks to the north south east or west into the void

i was going about my minecraft world in the end fighting the ender dragon and i was doing damage to it in the unlit portal while it was perched. As i was fighting it i must have either jumped or the game thought that i did and i was launched in a straight line away from the end island. Also when i say i was launched, i mean even if you had used an ender pearl you wouldn’t have had the reaction time to even see the island atleast in range to throw a pearl. I did not check my coordinates while i was going into the void out of sheer shock but i use a render distance of around 20 chunks and could barely see one side of the island once i stopped moving away and started to head down towards the void. Mind you i lost everything including my riptide III trident which is hard to get so you can probably guess why I'm typing this report. if you happen to see this and go over the bug please fix it, this has actually happened to me on a different occasion so it is definitely a problem. Thank you, -IsaaacPopMop. P.S. unfortunately i do not have any screenshots but replicating this glitch or bug rather, should be easy since I've had this happen twice now.
