Every Time I Jump In The End Gateway Block (/setblock ~ ~-3 ~ end_gateway) While In The End It Glitches Out.

It Glitches Out + Have To Use /kill To Deactivate

What I expected to happen was...:
All The Chorus Plants Grow

What actually happened was...:
I Get Stuck In Unloaded Area

Steps to Reproduce:
1. Go Into The End.
2. Get An End Gateway Block (/setblock ~ ~-3 ~ end_gateway).
3. Jump Into The End Gateway Block
