Constantly using riptide would eventually cause the sound and animation to stop playing. From my testings it occurs when you use it quickly or when nearing unloaded chunks.

What level of riptide do you have on the Trident?
Level 3
I can confirm
Confirmed, I've seen this occured for me a few times.

Are you still able to reproduce this in the latest version? After quite a few attempts, I was unable to.
