Looks like the stabAttack used when a Spear attack just check the result of damage (what can be cancel by the events...) for cancel the post attack effects... the knockback, dismount and stats are still called.

Then not sure what its the expected behaviour for this.. if the damage was cancel then omit the rest of logic or just a few of the logic...

PD: You try using the EntityDismountEvent?
