Describe the bug
Player head's position isn't correctly reset, causing players to potentially suffocate unexpectedly when just half-submerged in water from the client's perspective. This also makes using water buckets rather annoying

To Reproduce
Steps to reproduce the behavior:

1. Start a new world, preferrably in Creative mode
2. Get elytra, and wear it
3. Glide using elytra
4. See client-server mismatch error

Screenshots
After using elytra

This usually shouldn't happen

This issue also occurs server-side when you sprint swim in water for a bit.

Closed this issue, since it's a likely duplicate of #765.

What mca version do you use?
