Seeds that spawn you in the middle of the ocean cause lag

If you spawn in the middle of the ocean, the game will lag significantly more than spawning on land. Below is a jfr report made right after first entering a world using the seed -627081940333231321.

Steps to reproduce: 

1. Restart Minecraft
2. Create a new world with the seed -627081940333231321 (which spawns you in the middle of the ocean)
3. Notice that the game is a bit slower than usual
