Thrown tridents and snowballs are supposed to break chorus flowers, but they don't in Bedrock edition. Arrows do break chorus flowers (as they should). My understanding is that these projectiles all work in Java edition, so it's also a parity issue.

Steps to reproduce:

Grow a chorus plant.

Throw snowball or trident at the flower

Expected result: the chorus flower breaks when hit by a trident or snowball

Observed effect: the chorus flower is not broken by the snowball or trident impact

Snowballs would be particularly useful for automatically breaking the chorus flowers in farm (using dispensers to shoot out snowballs) because unlimited amounts of snowballs can be automatically farmed, while arrows are usually obtained manually. Also, even if one has a good source of arrows to use, many of them miss the target and can end up cluttering the player's inventory when they enter the farm to replant. Using snowballs, the harvesting and collection can be automated and only the planting would be manual.
