Bug with /gamerule spawnRadius x /setworldspawn

Expected behavior

When the /gamerule spawnRadius is 0 and /setworldspawn ~ ~ ~ is set to another coordinate than the normal starter World Spawn the players with no respawnpoint should respawn on the exact Block wich will be set with /setworldspawn ~ ~ ~. But if the /gamerule spawnRadius is 0 players respawn at the first world spawn.

Observed/Actual behavior

If you change the /setworldspawn ~ ~ ~ and do /gamerule spawnRadius 0 you should spawn at the befor set world spawnpoint.
When /gamerule spawnRadius is 0 the game spawns you somewhere else than the set Respawn Point.
When /gamerule spawnRadius is 1 or more the game spawns you at the world spawnpoint wich was changed bevor.

Steps/models to reproduce

1. Mark the normal World Spawnpoint.
2. Go to another location. Mark and set the World Respawnpoint with /setworldspawn
3. Now set the Respawnradius with /gamerule spawnRadius to 0 and move away a bit.
4. Do /kill and you should spawn at the Normal World Spawnpoint.
5. Now set the Respawnradius with /gamerule spawnRadius to 1 or more.
6. Again do /kill and you should now spawn at the World Spawnpoint location set in Step 2.

Other

This issue was reported befor in the 1.20.4 Version of Folia but it is back again.
https://github.com/PaperMC/Folia/issues/222

Reproduce the behavior in Folia 1.21.8 using /setworldspawn, /gamerule spawnRadius 0 or 1, and /kill, then compare the two respawn outcomes. No source file or test is named; inspect the world-spawn and respawn handling reached by these commands, and consider the issue done when spawnRadius 0 respawns at the changed world spawn block.
