/setworldspawn not functioning properly across dimensions

When I use the /setworldspawn command in the nether (I have not been able to replicate this elsewhere though I believe it to be possible), then die anywhere and respawn, the game first puts me into a block, and after another death via suffocation it then correctly spawns the player at the intended coordinates. Replicating this is simple enough, go to the nether, do /setworldspawn, move to a different position and then die by any means. Expectation: after respawning, the player will be at the coordinates where the command was executed. Reality: for some reason the command only works after every second death, which is peculiar because after any death it misfunctions every time, and every time it works correctly after suffocation as opposed to spawning the player within blocks again and again.
