Caused by the fix of MC-133157.
You are unable to sprint using control when on the ground in one-high water, even when flying in creative and spectator mode. This is easily seen with the lack of FOV change clearly seen in versions 1.13-pre6 and prior.
In fact, some of the behaviors of MC-133157 occur when bobbing at the surface of the water, when the game allows sprinting in mid-air, but not in water.

This bug also makes it impossible to sprint in creative and spectator mode flying in one-high water.
You don't have to play the game very long to notice that sprinting in shallow water no longer works. It's really annoying and you need to go down a level to even start to sprint.
They should make it like 1.12 where if you sprint above water; your FOV changes but your speed stays the same.
Can confirm in 1.20.4, 1.20.5, and 1.20.6.
The FOV changing back and forth when holding both the sprint key and jump key while moving at the surface of a body of water is a bit annoying.
It's intentional that players cannot sprint in 1-deep water. Some bugs that were marked as duplicates of this bug might not be covered by this decision and might now need to be tracked separately.
this means depth strider is now slower on shallow water
