I came across this issue while attempting to play on a 1.14 SMP server. The hopper hitbox can trap you in a "crouch mode" (underwater) in which you cannot escape while in survival. The player seems to be forced in crouch mode without control to free from this mode.
Steps to recreate:
Go into a water 2 or more deep. Place a chest (or stone wall), place blocks on 3 sides, place a hopper above the chest. While swimming, swim up to the chest and stop. As soon as you go into crouch mode you are stuck and cannot move away.

I disagree with the current resolution. MC-148933 only mentions not being able to swim while sneaking.
This ticket has to do with not being able to escape that position nor the block(s) you are in while under water.
Specifically if it is a hopper over a water logged block that does not have a full (x,z) collision box, with blocks on 3 sides.
You sneak below the hopper because the player hitbox always tries to take up as much space as possible, and in this case, the maximum space it can take up is while sneaking. That is an intended change in 1.14.
You actually being stuck there hence is a side effect of MC-148933. You can actually move away, but only slowly (since you're sneaking).
That is incorrect. You cannot, in this case move away. Just try it exactly as described. These two tickets are related, but not the same. I have experienced the other issue, and can always move away, not with this one though.
Hmm, indeed. However I believe that that is caused by MC-149207, as the chest is waterlogged. If you look closely, it has a flowing water texture and behaves as if it was flowing water, while it shouldn't do that.
That combined with your speed being decreased while sneaking causes you to not being able to move.
You can move sideways though, so if you break the blocks next to the chest and the hopper, you'll be able to leave this state that way.
This is still a thing. Affects version 1.14.2, even though the status of MC-148933 shows as resolved. Something needs to change here. The status of the referred to ticket MC-149207 shows as open still. Perhaps if that were addressed this one might be fixed. Until then this ticket should be opened. A player should not have to break anything to get out of crouch mode if there is an open path to do so.
