Re-entering water while in a crawling state can cause the player to visually stand up

Relates to MC-129863 as this produces the same effect but requires slightly different execution.

How to reproduce

1. Set up the apparatus shown. (all water blocks are sources)
2. Sprint-swim through the water to the top.
3. Exit the water into the one-high space and switch into third person view.
4. Reverse back into the water and sink slightly.
5. Your character will begin to visually be standing up even though they are actually not and should not be able to due to the presence of blocks.
6. While the character is beginning to stand up, swim upwards to the top again.

This bug seems to be purely visual, but is extremely weird nonetheless.
