Jackal not 'disabling' and becoming vulnerable even after all four limbs destroyed (unwinnable fight)

Screenshots of all dead limbs and still invulnerable body:

Spoiler

Cause:

The Jackal does not immediately engage alerted AI upon spawning. If the player is in stealth and for as long as the player remains stealthed, AI will not engage (Jackal constantly tracks even stealthed players once properly engaged, walking to their location to collide and trigger a ground slam).

During this 'unalerted' AI the Jackal's limbs can be reduced to 0 hp without the body dropping into vulnerability. Doing so to all four limbs before leaving the stealthed state (and causing the Jackal to be alerted) renders the fight impossible to complete, as hitting 0-hp limbs (for 0 damage) will not cause the body to become vulnerable even after allowing the Jackal's AI to properly engage.

 

Ivaras able to overlap time in Cloak bubbles and other Stealth sources not broken by combat during which the player can successfully drop all four limbs to zero health without having to re-cast and dropping out of stealth for a second in the process, e.g. Loki Invisibility with sufficient damage output can encounter this mission-halting bug.

Remove mod on elemental damage with weapons (sentinel, if he is, too). It helped me.
