{}Players can respawn mid-air with default spawnpoint when blocks under spawnpoint removed.
This issue happens since 24w20a.
Steps to reproduce:
1.Create a default world. (eg. Use the seed:12, which default spawnpoint is at (-32,72,-32)
2./kill and respawn. (Due to MC-272333, the respawn point is always at the same X and Z coords)
3. /fill ~ -60 ~ ~ ~-1 ~ air
4./kill and respawn.
Observed result:
You will spawn midair and fall. (In survival mode, if the fall time is longer than 3s, you will die again)
Expected result:
You will spawn at the bottom (y:-60)
Notes:
Relates to MC-272333 and MC-272369(fixed)
In 1.21-pre1, you will spawn 1 block above ground if blocks under default spawnpoint not removed, this is also different from 24w19b and before.

I was unable to reproduce this, every time I kill and respawn I spawn somewhere next to the stone structure.
Update: I can confirm now.
BugTracker I can confirm, it happens to me all the time (tested in a superflat world, by the way).
Can confirm too.
This issue happens since 24w20a.
COMETC2021A1 > It will be fixed in a future update (probably the next, check the bug status).
