Player movement is not disabled during the attack animation of a riptide trident

The player is able to walk or run during the riptide animation. While this doesn't appear too unusual in first-person considering the player cannot see the external animation, it is definitely unusual from the third-person perspective, and gameplay-wise.

Steps to Reproduce:

1. Give the player a riptide trident

   /give @p trident{Enchantments:[{id:"minecraft:riptide",lvl:3s}]} 1
   

2. Set weather to rainy

   /weather rain
   

3. Change camera to third-person
4. Throw the trident while walking/running forward or downward
5. Continue to walk/run during the animation

Observed & Expected Results:

- The player is able to continue to walk/run during the length of the attack animation.
- The player would not be able to walk/run because they are in the middle of an attack animation.

Possible Fix(es):

This could be fixed by either putting the player back into the 'standing' state after they hit the ground when using a riptide trident (similar to how the elytra does the same), or disabling movement entirely until the player is standing upright again.
