Mob "Replicates on Death" mod in Blight

Was puzzled when I was still receiving damage after blight encounter ended.
Do not think this is a bug or the boss mod is common, but thought i would post an image here for reference.

Personally I hope GGG will review mechanics where player still receive damage after an encounter/boss fight ended. A related episode is Maven sometimes continues to cast skills on me after I kill the boss, and picking up the invitation did not help.

Some solace to enjoy picking up our loot would be nice. Thank you.
