EntityUnleashEvent is not fired under specific circumstances

[Dessie0]

Expected behavior

When an entity is leashed, and either of the following occurs:

• A firework rocket is used while flying with an elytra
• The lead is attached to a boat, and the boat is destroyed

These should fire one (or both) of the following with a respective UnleashReason:
EntityUnleashEvent/PlayerUnleashEntityEvent

Observed/Actual behavior

Performing either of the previous actions while the entity is leashed with a lead will not fire EntityUnleashEvent at all

Steps/models to reproduce

1. Lead any entity

2. Launch with firework while using elytra.

3. Lead a boat

4. Break said boat.

In neither case does EntityUnleashEvent fire.
