Sneaking prevents the player from moving with riptide

Summary:
Sneaking prevents the player from moving with riptide. The animation plays but the player remains in place. The player can also "bounce" but still stay in place

Steps to reproduce:

1. Enchant a trident with the riptide.

2. Set rain.

3. Start sneaking.

4. Use trident.

Observed results:
The player didn't move at all.

Expected results:
The player will move when using the trident and will only stop at the edge of the blocks (to match java).
