After getting into a boat, holding the emote button and choosing an emote you can now crouch in the boat and not get out of the boat. The only way to get out of the boat is by destroying it or leaving the world and joining back in.

Steps to Reproduce:

1. Spawn a mountable entity (boat, minecart, horse, etc.)
2. Mount the entity
3. Hold the emote button
4. When the quick emote menu appears, release the emote button
5. Try to dismount the entity by pressing the crouch button

Observed Results:
The player crouches and doesn't dismount the entity.

Expected Results:
The player dismounts the entity.

Notes:
For boats, you will need to use a controller.
