End Portal Re-Respawn Issues

Description

context: This happened after killing the Ender Dragon and then traveling through the End Portal back to the Overworld...then back to the End for Elytra.

After attaining my loot- I headed back to my original spawn point in the End to head back to the Overworld- alas, was not to be.

What actually happened:

After entering the portal, I was immediately returned to the original End spawn platform (obsidian platform). I tried again, then again...then I tried from the North, South, East and West sides of the portal. Then I stowed all my gear into my Ender Chest and hurled myself into the void- several times, yet always spawned back in the End.

I then took to the skies in search of a randomly generated End portal to see if that resolved the issue- it did not.

I am now stuck in the End...sustaining on Chorus Fruit and Endermen Essence.

What I expected to happen:

I expected to return to my spawn point in the Overworld

Reproduction:

1. Enter an End portal from the end
