If you use a riptide trident while gliding with an elytra you get the normal hitbox which is 1.8 blocks high after the riptide animation stops.
How to reproduce:
- Have rainy weather (use this command: /weather rain)
- Put on an elytra
- take a riptide trident
- use that trident and don't stop gliding during the riptide animation
- After the animation stops try to fly against a ceiling by holding space or using a rocket
Then you notice that you stop flying up lower than you should.
What I observed: You have the 1.8 blocks high hitbox after the riptide animation stops.
What I expected: You still have the small hitbox after the riptide animation stops because you are gliding.
