Harmonizer ragdolls instead of playing death animation if killed during Vortex attack

On multiple occasions, I have killed Harmonizers while they perform their Vortex attacks, and on those occasions they did not play the preset death animation, instead ragdolling onto the ground as if a normal enemy.

Expected result: Harmonizer should play correct death animation on all occasions.

Observed result: Harmonizer ragdolls onto the ground if killed during the vortex attack (while it’s summoning the orb).
