setworldspawn issue

the 11 report

When I was fighting underwater and withering, I set the birthing point of the world. But after I died and I was born again, I was born in the world's birth place

What I expected to happen was...:

After I died, I was born at the birth point of the world I set up.

What actually happened was...:

The world birth point I set up is not effective. After I died, I was not born again in the world born point I set up, but the birth point after the creation of the world.

Steps to Reproduce:

1.set the world births at a distance from the birth place of the creation world

2. When you set it up, open the chat bar

3. using the Kill Command

4. click rebirth key after death

5. opening the debug screen, you can see that you are not born at the birth point you set up, but the birth point of the world
