Oskarm Assassin's Mark error

Hi, I am reporting a mechanical inconsistency regarding Oskarm (Unique Nubuck Gloves) and General's Cry (Lacerate of Butchery).

​[Current Setup]

​Main Skill: General's Cry linked with Lacerate of Butchery.
​Weapon: Uul-Netol's Embrace (Vaal Implicits: Curse Enemies with Vulnerability on Hit).
​Gloves: Oskarm (Trigger Assassin's Mark on Hit).
​Amulet: Ashes of the Stars (Corrupted Implicit: Enemies can have 1 additional Curse).
​Total Curse Limit: 2.
​[The Issue]

My Mirage Warriors from General's Cry successfully apply Vulnerability from my weapon (Uul-Netol's Embrace), but they fail to trigger Assassin's Mark from the Oskarm gloves.

​[Key Argument]

Since Mirage Warriors inherit all of my equipment's stats and "on-hit" effects-as proven by the weapon's Vulnerability applying correctly-Oskarm's Assassin's Mark should also be applied by their hits.
